There's s difference between gelatin and jello.
I'm talking about this stuff.

Or something similar. It shouldn't change it. It has no flavor on its own and won't water anything down.
Yep, just buy one of these and your beer will be forever clear from now on. https://www.amazon.com/Knox-Unflavored-Gelatin-1-lb/dp/B001UOW7D8/ref=mp_s_a_1_4?crid=N6U0DATX0HMZ&keywords=gelatin+knox&qid=1656867169&sprefix=gelatin+knox%2Caps%2C94&sr=8-4
so by gelatin you mean something like this?
(forgive me for never knowing there was a jello besides the jello kind)
This place has bulk unflavored gelatin in 5lb and 25lb quantities. Not sure if this would work, but it saves you from opening a thousand little packets.
Amazon has 1lb cans of Knox brand gelatin.
