Can the welding assessment for 12Cr1MoV be applied to 12Cr1MoVG and 12Cr1MoVR?

A weld assessment was conducted for 12Cr1MoV, but the pipes used for the container are of type 12Cr1MoVG; I was wondering whether the weld assessment for 12Cr1MoV can still be applied

Applicable (see Table 1 of NB/T47014).

The material can be covered. It also depends on whether the wall thickness is sufficient

Materials in the same group can be used interchangeably, but their scope of application should be consistent.
