Dear @lee_bohwa ​, hello.
Welcome to Chaos Forums!

Some camera types are hidden from V-Ray 3 on.
Due to customer requests the choice from the user interface is now possible via script.
This post from Peter is explaining how it should be used.

Please take a look, make some tests and contact us again if further assistance is needed.

Wishing you a happy day.
Best regards,

Oh I understand.
Thank you for your help!
