I know it is not recommended, but is there a way to skip
fsck checking the file system mounted at

You can put
0 (or nothing) on the sixth field of
/etc/fstab for the root filesystem to disable
/ on next reboot.
UUID=foobar / ext4 errors=remount-ro 0 0
Again, as you have said this is not recommended absolutely.
man 5 fstab:
The sixth field (fs_passno): This field is used by the fsck(8) program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. Filesys‐ tems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked.
