I already tested on all OB and the lastest stable OOS11 and Widevine stay in L1, even in ROMs Widevine will be L1 if you use any OOS11 stock ROM as baseIt's hit or miss. I couldn't get L1 with unlocked bootloader, no matter what.
The only way to get L1 back in my case is to lock the bootloader and go back to official.
Are you suggesting to update from an Android 10 L3 unlocked state to Android 11?
With Magisk already on it?

So, my recommendation is make a backup of your stuff, take off the fear and try by yourself.
I don't think that it's working just for a specific variant, maybe there's something we are missing.I'm trying.
But every effort in getting L1 on an unlocked bootloader was without success...
This is why I'm asking. The only difference I can spot so far is that you have a GM1917 and I have a GM1913.
Tried everything with Magisk, without Magisk. Nothing was successful.
I am also in the same situation, I tried everything but with unlocked bootloader I have L3. I have a GM1917I'm in the same situation as you and I have a GM1917. It goes to L3 once I unlock the bootloader. I have Magisk with Magisk Hide enabled and it didn't work. I'd think that this is the normal situation, though...
