Or, if can’t avoid it, use it but you cut the wifi and other crap and connect your own router on it.
I use the Turris Omnia since a good decade now, still supported, open source based, i can put some services on it (vpn, ssh, nas, speedtest, ...), put some traffic rules / ports redirection, firewall, dns, hostname/ip per mac address, pihole, wifi conf, etc...
If i switch to another ISP, I change the box and everything rework quickly...
Check also the codec to avoid filling your hard drive in 5min. Depending on your video card, you could use nvec, x264, ... codecs (in the recording tab)
Do some tests (including opening it in your video editor) to avoid bad surprise
If don’t have a video editor in mind, look for davinci resolve, it’s free and a very good tool.
