GNU/Linux: can not select AV1 video format for various video encoding/streaming
I have a GNU/Linux (openSUSE Tumbleweed) system with fully functioning HW video encoding (even AV1, in addition to, h264 and hevc) using VA-API on AMD Radeon hardware (using opensource Mesa 3D drivers) in all applications like OBS, KDenlive...

But it looks like Steam Client is NOT supporting selecting AV1 video format for any video encoding/streaming. For example in Settings → Remote Play → AV1 Video setting is greyed out and disabled and I can not enable it. And in other places I can not even see any option to select AV1 video format for hardware encoding.

I tried to even install 32-bit VA-API libraries, Mesa, and GStreamer libraries and similar and this did not help.

Basic system info is this:
