Low headphones volume

[Genius1337]

So I have a Redmi Note 12 Pro and the volume in my headphones just isn't loud enough.
I understand that it's an EU regulation thingy, however nothing I tried seems to work.
On my Redmi Note 7 I fixed it by changing the region, here however that doesn't work. What can I do other than root?
Also I'm not speaking about bluetooth headphones, the absolute volume wouldn't work, I don't even have that setting.
