For your nofail option you way want the mount-may-fail? option¹. If you
want to check the source for what mount options are supported, its in
(gnu system file-systems), and the list is

(known-flags '(read-only
               bind-mount no-suid no-dev no-exec
               no-atime no-diratime strict-atime lazy-time
               shared))
