Is there a way to toggle pressure sensitivity ?

I was trying to play MGS3 with a switch controller but all my presses where too light for some reason (I also played MGS2 with this controller and it worked fine). I started using the pressure sensitivity mode in the pad settings to make all presses 100% but I have to hold down the pressure sensitivity button for the presses to work. I was wondering if there is a way to change the strength of all my presses or if I can toggle the pressure sensitivity button ? I tried to post this question on reddit yesterday but until now I have gotten no response and I am itching to play MGS3.
