Have to say that I agree with Whopity on this one. Under JAR-FCL you were required to be a unrestricted FI to remove the 'no applied instrument' instruction restriction last stated in LASORS 2010 H1.4. However, under EASA this no longer applies.
As Whopity says, it's not listed under the restricted privileges in FCL.910.FI.
