Yes, this is primarily a bug in the Depends on the wireguard package:

    Depends: wireguard-modules (>= 0.0.20191219) | wireguard-dkms (>=
        0.0.20200121-2), wireguard-tools (>= 1.0.20200513-1)

The linux-oem kernel has (separatly) a bug in its Provides so it does
not think it contains wireguard.ko.  In that scenario we want the apt
resolver to pick wireguard-dkms as at least that way you have a
wireguard.ko.  But the way it is formed it will pick wireguard-modules
for installation if neither is installed already.  This can only be
solved by installing an unrelated kernel.

Am working on solving these problems variously.
