Radeon pro w5500 green screen issue on Mac mini 2018 with BigSur (11.6.1)

Hi, I have a problem with eGpu with Radeon Pro W5500 graphics card. Is there a new driver for this g. card using in BigSur? I've found on some forums that supported driver was only in OS Catalina.

Graphic cards with GPUs NAVI 10 series are perhaps supported in Monterey. Could be a solution of green screen problem if I upgrade to Monterey?

If is there some other solution how to fix this problem in BigSur please help me.

Thanks
