Having device tree sources in the tree doesn't mean that a SoC is supported.

Other people have reported success booting RK3588 systems using UEFI.

If you are using UEFI then NetBSD will not be using a dtb at all,
configuration will be done via ACPI.

The device drivers that use ACPI can be more generic than those that
directly control hardware.
