Can Sasuke use Amaterasu with his Rinnegan?
Sasuke can and still does use Amaterasu in the era of Boruto, so it definitely wasn't overwritten. I think he still has EMS in both eyes, the Rinne-Sharingan is stated to have the powers of a Sharingan as well.
In addition to the Rinnegan's power, this eye retains the abilities of Sasuke's left Mangekyō Sharingan, including the ability to cast ocular genjutsu and use Amaterasu.
With his left Mangekyo eye, he can cast Amaterasu. With his right one, he has the ability to shape the flames and even extinguish them.

With either eye, Sasuke can cast Amaterasu, as well as shape and extinguish them. Because he awakened both of his Mangekyō, he can use Susanoo.
The Rinnegan is one of the most powerful dojutsus and has allowed Sasuke to perform some impressive sets of techniques that he can no longer perform. Without the Rinnegan, Sasuke would be much weaker when compared to his best form.
As Urashiki continued his chase after Naruto's Nine-Tailed Fox chakra, Episode 134 of the series showcases this Blue Rinnegan's power in full which allows Urashiki to jump back and forward in time and replay events as much as he wants in order to choose the best course of action.
In fact, by Part II, Sasuke Uchiha has managed to master the Chidori to the point of not needing a single hand seal to invoke it and could use Fire Release techniques with only one hand seal.
One such element was Madara's EMS ability – the power to reverse time. The animation showed Madara's EMS spinning uncontrollably, resulting in everything moving backwards. This was revealed to be time reversal, a direct ability of his Eternal Mangekyo Sharingan.
1 Rinnegan
As a result, Sasuke's left Mangekyo Sharingan became a Rinnegan. This eye is known to be the strongest of all the Three Great Dojutsu in the Naruto world and it grants Six Paths powers to the user.
Sasuke is unable to use any kind of Sage Mode.
Is Naruto weak without Kurama?
Without Kurama, Naruto lost a big part of what defined his strength, and what also made him who he really is.
Sasuke's Rinnegan grants him two unique abilities: “Space-Time Ninjutsu and Amenotejikara.” Space-Time Ninjutsu allows him to manipulate space and time in a continuous sequence. By perceiving distortions in the flow of time, he can manipulate certain points in space.
The Rinnegan can absorb any and all NINJUTSU. However, Amaterasu is a doujutsu power, it's not ninjutsu. It requires no hand seals and you can't learn it. It's pretty much the definition of not being ninjutsu.

Sasuke's Amaterasu originates from his left eye however, and C indicates he is more skilled with it than Itachi; he can put out the flames with greater ease and can even manipulate the flames themselves as part of the "Blaze" element.
6 Sasuke Can: Genjutsu
He is undoubtedly the best genjutsu user in the series currently, and he can cast powerful genjutsu. Sasuke can use his Eternal Mangekyou as well as the Rinnegan to cast genjutsu. The Rinnegan genjutsu is very powerful as it even affects tailed beasts easily.

As such, awakening the Rinnegan is only possible for their reincarnations, or someone making use of their chakra. Madara Uchiha became the first person to awaken this eye when he was Indra's reincarnation.
One of the Three Great Eyes in Naruto, the Rinnegan is the strongest eye of them all. It was first said to be wielded by Hagoromo Otsutsuki, the Sage of Six Paths. Using the Rinnegan, the user can learn any jutsu they want and they gain access to special abilities and techniques commonly known as the Six Paths Powers.
