Virtual Machine in One Resource Group and NIC/VNET in Another Resource Group - Supported Azure Design and Required Permissions?

How to create both NIC and VM in VM resource group please guide with exact details step by step procedure-all possibilities if not possible lets us know the exact reasons?

Earlier we were able to create both NIC and VM in Networking Resource Group (RG): ABC but client requirement is to have as like below

ex:

Custom creates network interface-to search for vnet and subnet values

Networking Resource Group (RG): ABC

VNET: uks-nonprod-ABCD

Subnet: InfraSubnet

1.But we now need to create both NIC and VM in DEF RG as shown below, is it possible from azure side?

VM Resource Group (RG): DEF

VM Name: UKS-DEV-AIA-08

NIC Name: UKS-DEV-AIA-08-nic

2.Can service principal account be given cross resource group (RG) permissions to create such NIC and VM one or both in different and same RG?
