Changing the volume group during provision

I would like to change the volume group name on provisioning. Changed the partition table “Kickstart custom” and provision template " Kickstart default PXEGrub2" to modify the volume group. I’ve keep modifying those both template yet not working instead still use the MAC address. Im still new and learning the foreman. Thank you in advance.

able to change the volume group since the partition tables

[Kickstart custom]

had autopart if the condition fails. Need to add the "part /boot/efi --fstype="vfat" --size=200 --ondisk=sda"
