AX9000: is it possible to get the lower 5 GHz band radio (QCN9024) to work on recent OpenWrt?

Hello everybody!

Has anyone managed to get the lower 5 GHz band radio (QCN9024) to work? I'm on the currently latest stable release of OpenWrt (23.05.2): the radio doesn't work out-of-the-box, and the workaround from the wiki - https://openwrt.org/toh/xiaomi/ax9000#potential_issueslimitations - doesn't help also.

Thanks in advance!
