The problem here is that the non-RM licence does not exist anymore.
The default/RTP resources never had a licence for use outside RM, they were always RM-only.
For other shop resources there was a time when you could purchase them with a non-RM licence for a much higher prices, but that option does not exist at the moment.
If you have one of those old non-RM purchases then you can use them according to the different EULA you got with them two or three years ago.
Other than that, no, currently everything is RM-only.
