it's weird BT works at all, haven't tried myself, but apparently usb connection is essensial for BT to work, even the manual say explicitly to connect the usb cable: https://download.gigabyte.com/FileList/Manual/card_manual_gc-wb1733d-i_20241120.pdf
as for wifi itself i'd try to enable the M2_2 port and take the disk out of it
alternatively you could try using some risers to access x1 port under the GPU, but then using usb adapter would be a lot easier
Same with people who boast about never reading a book
