You should be able to. Also, look at Vulcraft design tools on their website. Has an unshored cant. tool for composite deck.

The only thing that comes to mind is that this is probably appropriate for a UDL but may not be appropriate for a point load
Wind uplift on a metal deck - sure
Footfall at the end of a cantilever? The local effects of the point load may cause a different failure mode to govern

This insight brought to you by my recent experiences walking on shipping container roofs, which are pretty similar

Sometimes crippling can govern over flexural yield, not sure why that would be difference for the cantilever case vs the simply supported case.

They state in the older manuals that the negative moment steel needs to be designed per ACI for cantilever. https://vulcraft.com/catalogs/Deck/VulcraftDeckCatalog2008.pdf

The OP has not stated whether this is concrete on metal deck or just bare metal deck
