All Macs running Big Sur have a set of Radeon kernel extensions (drivers) installed, but when you look at the binaries they're x86-64 only, not fat binaries. Rosetta can't translate kernel mode software, so for now Apple Silicon Macs cannot use external GPUs.

Apple hasn't informed users about future plans in this area, so it's unknown whether a future macOS update will include arm64-compiled Radeon KEXTs and thus restore eGPU support.

Hopefully it's just a delay. GPU drivers are generally the most complex kind of driver in the system; it's plausible they just weren't ready to ship. Even some of the much simpler drivers which did ship have some issues. For example, some of my USB disks don't work on M1, but do work on Intel Macs.
