OVMF is only relevant here if the FAT32 filesystem hosting the file that you're trying to rewrite hangs off the end of a driver chain that OVMF participates in. As in, if there's a virtio-scsi or virtio-blk device that backs the guest-side file. In these cases code in OvmfPkg is indeed relevant. However, these virtio drivers don't deny write access on their own, they only "forward" read-only status if you asked qemu on the command line to present the drive as read-only. Other drivers (IDE etc) could be doing the same to you, given similar (r/o) qemu drive configuration, but the code for those drivers is outside OvmfPkg.
