Installing proprietary AMD drivers on Ubuntu 20.04

I just installed Ubuntu 20.04 on my new laptop, and I would like to install the proprietary drivers so I can use gamma correction.

CPU: AMD Ryzen 7 4700U
GPU: Integrated Graphics Renoir

Output from lspci

$ lspci -v | grep VGA -A 1
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Renoir (rev c2) (prog-if 00 [VGA controller])
Subsystem: Acer Incorporated [ALI] Renoir

I tried to use the Software & Updates manager, but no proprietary driver shows up.
I also tried to visit the product's page to see if a linux driver was downloadable, but nothing.

I can provide any other information if needed.

Thanks in advance !
