You can Skip getting the Grapple Hook by using the Helix Blend Glitch in Memory 8.

Havent found a way to progress in the level after that, as you need the Grapple hook, tho.

There is a better way by glitching through the wall beneath this one! The Guards in the next area wont spawn, making it possible to progress. You can do the Sword&Gear skip after this. You cant progress after the sniping section, tho.

Sadly, only Grapple Hook Skip alone doesn't work, as you need the Grapple Hook when getting the sword, to get out of the room (and also later).
