Developer Mode on Quest 2 without app?

I have a Quest 2 and an Oculus account. I don't have a Facebook account (and can't get one).

Is there any way to set up developer mode on the Q2?

I activated the Q2 using an older version of the Android app. So I can connect to the store, download games, etc. But the Android app doesn't show the Q2 as being available, so I can't go into settings and activate developer mode.

I use Linux - so can't use the Developer Hub app.

Is there any way around this?
