"modinfo rtw_8822bu" will give you some info on the driver, though
no direct info on how it was installed. On Debian (not RPiOS) I see
there are similar modules starting with "rtw88_" installed with the
base, but no "rtw_8822bu.ko". rtw88 apparantly supports your
TP-Link Archer T3U RTL8812BU device:

https://deepwiki.com/lwfinger/rtw88/1.1-supported-hardware

Check if you have rtw88 drivers already installed:
 cd /lib/modules
 find -name 'rtw88*'

If so, maybe you just need to blacklist the rtw_8822bu driver to
use them? Unless the rtw88 driver is used already and it wrongly
logs as "rtw_8822bu", in which case the "modinfo rtw_8822bu"
command will fail, and look at the output of "lsmod" to see
exactly which "rtw" module/s are being used.
