Leaky faucet help

Should there not be a shut off for the water for this bathtub? This is in a mobile home and I’ve done work on houses but never a mobile home before. Opened the side panel, no shut off. Went underneath the home, didn’t see a shutoff either. Can I replace this without shutting the water off?

Also we are moving in a month and have a shower in the same bathroom so if I can locate the shut offs I can just turn it off as well.

Any help would be appreciated!
