From the details shared i suppose you mensioned that you see no related commands in the configuration to mac-vlan-permit.
For example i have attached a picture below.
From the details shared looks like you have checked the configuration in vlan and interface and dont see any mac-vlan related commands in the configuration is what i undretsnad. Correct me if i am wrong.
I did try looking into security guide for 8030 and 8090 and looks like the mac-vlan commands are only available until code 8030.
