OpenBSD on Radxa ROCK 5 ITX, RK3588 8-core CPU, Mini-ITX Motherboard

[Tito Mari Francis Escaño]

Good day misc,
Has anybody been able to install OpenBSD on Radxa ROCK 5 ITX, RK3588 8-core
CPU, Mini-ITX Motherboard?
I see support for Radxa ROCK 5B, and I was hoping to build a custom PC
based on this board and install OpenBSD ARM64 on it.
Please advise on possible challenges when installing and using Radxa ROCK 5
ITX and/or ROCK 5B.
Thank you.
