just be aware that the GN version does not accept any cumulative updates, whatsoever, so you'll always have to remain on the original version of GN as long as possible, no way to overcome this
And KMS_VL_ALL v14 will also activate it (if it is needed at all, i've seen it activate by just inserting the gVLK), i would never activate windows by an illegal external KMS server.
All is promoted at the OP, if it's not there then there are ddl via Techbench Unlocked download options or SVF patches.
