I can't for the life of me find a setting I wish I hadn't disable

Hey all!

Just got a Galaxy S10e about a week ago. I was messing around with some settings and initially thought it'd be annoying to have the fingerprint sensor of the power button always read allowing the phone to unlock simply by putting my finger on it. But now, I'm realizing for the long term durability it'd be a good idea.

For the life of me, I can't find it in settings to change it back! Anyone know what I'm talking about and can help?

To Calrify: I use to not have to click to get the sensor to read my fingerprint. I changed something thinking I'd prefer having to click (I'm coming over from an iPhone). I would like to not have to click the power button to get it to read.

Thanks in advance!
