If the thought is to slightly overcarbonate to compensate for lower PSI which will flatten, I wouldn't bother. It takes some time to do either. You could just lower it for the party to slow the pour and possibly reduce foam. The beer isn't going to go flat in a few hours or even 12 hours. Just turn it back up to normal after the party is over, if there's any beer left.

Sometimes when I reflect back on all the beer I drink I feel ashamed.
Then I look into the glass and think about the workers in the brewery
and all of their hopes and dreams. If I didn't drink this beer, they might
be out of work and their dreams would be shattered. Then I say to myself,
"It is better that I drink this beer and let their dreams come true than
be selfish and worry about my liver."
