blocked by admin policy.
Reviewed-by: Miao-chen Chou <[email protected]>

The following test steps were performed:
1. Set ServiceAllowList to []
2. Verify AffectedByPolicy of K830 is False
3. Set ServiceAllowList to
["1800"]
4. Verify AffectedByPolicy of K830 is False
5. Set ServiceAllowList to ["1800","1801","180A","180F","1812"]
6. Verify AffectedByPolicy of K830 is True
