How to remove modbus PV Inverter?

I’m testing with the Sunspec modbus PV inverters and after some changes I would like to remove them and add them again, but I can’t find how to remove them..

I already deleted the ip address and the modbus port and unit id. I also tried a reboot without any luck.

How do I remove these?

Not completely certain, but I think on the settings>devices page, there is an option for removing devices that are no longer detected.

I tried that, they disappeared from the devices page but not from the modbus inverters page
