Yuzu/Suyu . "custom drivers unsupported" no GPU

Hello everyone,

I recently bought a Retroid Pocket 4 Pro + and installed Yuzu as well as Suyu. In both cases, a lot of games are buggy... So I did some research and saw that I needed to install new GPU drivers, but I cannot do that; my section is greyed out, restricted, and it tells me "Custom drivers not supported." "Loading custom drivers is currently not supported for this device."

I’ve read a lot of articles and watched many installation tutorials on YouTube, and I don’t understand why this option is disabled. I don’t get it... In all the tutorials, the section is immediately activated.

Despite the updates and the DLC installed, half of the games are buggy, and I'm quite disappointed... I’m throwing this bottle into the sea; if anyone has ideas or explanations, I’m all ears.

Thank you for your attention, have a good evening!
