Nanitic Interfacing
Source
Starfinder Enhanced pg. 55
You can use your nanites on mechs you pilot, making them an extension of your own body. You can apply the effects of your sheath array to any mechs that you are piloting. Once per combat, you can spend a nanite surge to give the mech a number of temporary Hit Points equal to your nanocyte level; the mech loses any such remaining temporary Hit Points when the sheath array ends.
