If it's a sensor flusher, and you're able to hang a piece of TP over the sensor (like it's not built into the wall or anything), you can do that to keep it from flushing when you're not ready.
Then when you're all done, just remove the TP and toss it into the bowl for the auto-flush as you're walking away.
You can hang them on the in-wall type too. Just wet a small spot on the tp (don’t use toilet water, ya gross), and stick the wet spot to the wall. It’ll adhere and drape the tp over the sensor.
