Sure, the mount options are (mkfs.f2fs -s64 -t0 -a0 btw).

   -onoinline_data,noatime,flush_merge,no_heap

I ran fsck, and it have all "Ok" messages, I can run it again, but would
avoid it if all you want is to know whether fsck shows a problem, but can run
it again if it is of any interest (the disk is in near-constant use):

The two directories have not changed since then:
