[chirp_users] How do I ensure that I don't TX on a memory slot? Baofeng UV-5RX3

I thought I saw something about what column to set earlier when I was looking for something else, but can someone give me a hint as to what I need to set in order to disable TX on a particular memory slot that I want to be listen only (specifically, in this case, the US WX frequencies)? — With greatest regards, Geordon Shōshin 正心 VanTassle
