There are two gaps across from each other, and there isn’t a 10mm Allen where the axel goes through. I’ve tried pulling it off, and hitting it through the non drive side but nothing. And tried loosening it, if it’s threaded, with the two notches where the bearing sit.

I can’t say for sure but the outer casing looks similar to the Shimano XT freehub body and that requires a 14mm allen
11mm is common on unbranded qr hubs.
The 2 notches are for dismantling the freehub body itself
As noted,11 or 12mm Allen wrenches are sometimes used on non-shimano hubs. You find whatever the biggest wrench fits from either side and that’s it. Some unscrew from the hub, some you loosen a captured nut that stays inside the hub. Everything is a right-hand thread, but depending on if it’s the captured-nut style or the screwed-into-the-hub style you have to turn the wrench differently.
Angle grinder.
Are you absolutely certain there’s no hex or “double hex” shaped hole in there? I can’t tell with all the grease on it. The hex hole will sometimes be sat further inside the freehub as well. So **really** make sure.
https://www.reddit.com/r/bikewrench/comments/18ybopk/what_socket_is_this_in_this_shimano_freehub_body/ much like this one. If it’s a double hex, a standard allen key will fit. They just use double hex to allow for greater clearance when fitting the axle in.
Recently did this myself, you’ll need a special freehub removal tool as seen here: https://youtu.be/iATTc9koBl4?si=DwhwawnvAt2K99XK
