Hello,
Thank you for posting in Q&A forum.
To further troubleshoot this issue, please kindly try below steps:
1.Navigate to Group Policy Management > Computer Configuration > Policies > Windows Settings > Security Settings > Restricted Groups and adding the Network Configuration Operators group and make sure the group is configured well with proper permission.
2.From adapter side please check if it supports non-administrator users modifying VLAN IDs.
3.Try to configure the VLAN ID by CMD command or shell scripts and see if it works.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best regards,
Jill Zhou
