Which Shimano hub is used in Xlab discs? Want to remove freehub body

Just wondering if anyone happens to know which hub is used in the Xlab Disc 2.0.
Its the lenticular version that looks like this one:

The only markings I have found are on the non drive side and say Shimano Japan.

I can’t seem to locate the disassembly notch in the freehub body or a fixing bolt of any sort.

Not sure but I’ll take a look at mine when I get home tonight…see if I can give you any insight
