This means the driver doesn't support this variant of the hardware.
It's not a firmware problem.

That appears to be fixed in 5.12 by:

commit 5d6651fe85837b11564a2e2c3c6279c057d078d6
Author: Guo-Feng Fan <vincent_fann@realtek.com>
Date:   Tue Feb 2 13:50:12 2021 +0800

    rtw88: 8821c: support RFE type2 wifi NIC

but that may depend on other changes.

Ben.

Will this fix be ported to bullseye?

Michele.
