Can you damage a graft by applying pressure?

I had an FUE in 2021 and the result were okay. I have very fine hair and not great donor reserves, so it turned out probably as good as it could have, which is still a huge improvement. During the first two weeks, my head was VERY itchy. Benedryl did not help. Starting on post op day 7, I applied some pressure to the itchy areas with the pads of my fingers (not enough to break the scabs). If the graft stays in place, can you still damage the graft with this pressure? If so, how likely is it?
