Temporarily cap PEX pipe while laying new flooring?

I am remodeling a bathroom. We’re going to lay new tile and replace a vanity. This requires removing the toilet and old vanity. In order to remove the old vanity I need to cut the PEX piping attached to the shut off valves for the faucet.

I have PEX caps and cinch rings, do those hold well enough so I can turn the water back on for a few days until I can get the new vanity installed?
