That video changed.
I’m linking the similar video, from the same content creator, it’s in german but Youtube can translate good enough for you. He does it on CasaOS that is basically the same, the solution is also the same and it worked for me but eventually I gave up fixing and customizing ZimaOS to my liking and moved to TrueNAS. ZimaOS is good as long as you keep it basic and don’t want to customize stuff like this.
