Cycling back to my other idea with the new PCIe node. Here was a similar one added to mainline device tree for another RK3588 board: rockchip-rk3588-edge: add ap6275p support by efectn · Pull Request #6335 · armbian/build · GitHub
Ah, and here: rockchip-rk3588-edge: opi5b: add support for pcie wifi by efectn · Pull Request #6486 · armbian/build · GitHub

Checking our kernel output:
[ 3.682659] wifi_disable: no parameters, enabled
[ 3.682722] reg-fixed-voltage wifi-diable-gpio-regulator: wifi_disable supplying 0uV
Interesting node wifi_disable which is indeed defined without status attribute. It sounds like, when enabled, it would disable WiFi. But this is also present in 5.10 sources and not changed anywhere.

It seems the same happens with the same WiFi module on Radxa ZERO 3: Share of Unofficial DietPi - Radxa Zero 3W
