A restricted FI can't do anything without the constraints of an RTF soon to be ATO and a supervising FI. If you want to operate freelance then a CRI is a better rating technically as it has no restrictions. However a CRI can't do abinitio or night so could not do trial lessons.
I thinks it's a bit of a surprise to a new FI(R) how little they can actually do generally, which may indicate a failing in the training system.
So to answer your question, No.
