Looking to remove interfaces from my RES 3700 V 5.4 MR1

[One of One]

I've got these three interfaces that we used to use with another piece of software that I would like to disable. Is it as simple as removing the rows from this table? Right now if I don't have the old software running after a check is paid or sent, there is an error that it can't communicate with the interface and it timed out even though there is no information that would need to go back and forth to the other system.

Any help appreciated. I'm worried if I get rid of the rows I won't be able to get them back.

You can check your touchscreen if the interface is tagged to any

So if the isn't in use on any currently used screen, I can safely remove them? And is the interface screen the only place to do that or is there some other location (ie config file) that is hiding in the folder structure?

also, you can confirm that there are no smart keys tagged to your SIMs
