How to change IPS tag of domain?

I am transferring one of my domains away from Squarespace to Hostinger. I need to change the IPS tag in my Squarespace domain, but I can't see an option anywhere.

I have unlocked the domain lock. Has anybody have any ideas on how I can enter the IPS tag please? Thank you

Did you manage to do this? I can't find anyone to help me do the same thing ..
