Help on disabling person button in PA30

Hello Abap gurus:

I got a requirement to disable(hide or remove) the person button which appears when i navigate in below manner:

In Pa30 enter a person number and select IT 212 COBRA plans overview then select any record and go to change mode which displays a Tab script with four tabs namely(plan cost, costs, Dependents, and additional data) so Under Dependents tab there is person button which i need to disable.

Please help in solving this issue.

Thanks and Regards,

Sravanthi.
