Are you using WebXR? If so, https is required. There are other topics you might search, including the web.
I went with the certificate from a fake certificate authority I created. In windows, you add the authority. On the dev I use, Quest2, I still get the warnings to go thru every time I reboot. Many people may not be comfortable with pulling that off, but I had done it before, years ago.
