Is it necessary, and how exactly, to specify TimeStamp when signing an RDP file?

Question

RDP

When signed by MSI. EXE. scripts and other things, if a trusted time stamp server (TimeStamp Server) was not used when signing, the signature ceases to be valid when the certificate expires. If the server is specified (and the timestamp is received), then the signature remains valid after the certificate expires.
Tell me, does the signature of the RDP file become invalid after the certificate expires? Is it possible to somehow sign a file with a "timestamp", given that the RDPSign utility is used for signing, and not standard tools, and the utility does not know anything about the TimeStamp server (there is no such parameter).
And in general, is the "Like Code Signing" mechanism used for signing, or is it a regular signature?
