PSAvoidUsingConvertToSecureStringWithPlainText how can i encrypt plain strings then??

So, im trying to convert a string to a securestring, so it can be secure when i serialize it to disk. How am i supposed to do it with doing:

ConvertTo-SecureString -String 'EncryptMe' -AsPlainText -Force

In my situation, i am getting return data that is a string, i cannot prompt the user to input it as a pscredential or something as the user does not know what it is. But after i have the data, i want to secure it, hence, convertto-securestring. Please advise how i can do this (ideally without just using ExcludeRule).
