Is it possible? I searched user guide and other article on internet, and only that I found commands are add_capture_mask & add_net_connection. those could mask but not mask only input. I am a student, so it takes much time for me to find correct command. so if you have any experience please tell me anything. Thank you for your answer in advance.

Do you want to constrain port such that bidi port will work as only input port? Please clarify.

If you can able to solve bi0di pad issue at logic stage, thn it is more preferable. If pad enable pin is coming from top level than you can control through top level itself.
