Problem detecting tbs pcie cards-Ubuntu 20.04.5 /kernel 5.15

Hopefully the problem is easy to fix on basis of the info below.

Computer : Lenovo Thinkstation P330 gen2

Tried with PCIe speed auto and gen1.

lsb_release -a
Distributor ID: Ubuntu
Description: Ubuntu 20.04.5 LTS
Release: 20.04
Codename: focal

uname -r
5.15.0-58-generic

lspci
01:00.0 Multimedia controller: TBS Technologies DVB Tuner PCIe Card
03:00.0 Multimedia controller: TBS Technologies DVB Tuner PCIe Card
(both pcie cards verified ok in windows 11)

Drivers seems to be successfully installed in:
/lib/modules/5.15.0-58-generic/updates/extra/media
-No errors during the process

lsdvb
lsdvb: Simple utility to list PCI/PCIe DVB devices
Version: 0.0.4
Copyright (C) Manu Abraham
ERROR: Opening /sys/class/dvb directory


dmesg | grep -i 'dvb'
nothing is detected

I have followed this guide https://github.com/tbsdtv/linux_media/wiki

I have installed linux drivers successfully several times before in ubuntu 20.04 (kernel 5.8) but then the drivers gets located in
/lib/modules/'uname -r'/kernel/drivers/media
