Yealink Phone Lock settings

[IT-Risch_Support]

Hello! We have a phone which is situated in the conference room. Yealink T48S
We have applied following settings:
phone_setting.phone_lock.enable = 1
phone_setting.phone_unlock_pin = xxxx
phone_setting.phone_lock.lock_time_out = 60

Can we somehow setup that the phone doesn't show the incoming number / contact until we unlock the phone when the phone rings?

At the moment we have to put the phone in DND mode to prevent visitors to see the incoming call contacts.
