No way to separate the alarm volume from other volumes in iPhone 13?

Greetings,

I travel a lot for work and am in different time zones. Therefore some times I receive texts and calls at times when I have to sleep.

I need to turn off the ringer and notifications volume to be able to sleep uninterrupted but that also turns the alarm volume down.

I have read that it's not possible to separate those volumes in the way Android phones can but it seems irrational to me that iPhone developers haven't come across literally thousands of people with exactly the same problem.

Is there really no way to keep the alarm volume on high while silencing everything else?

Thank you in advance.
