Unfortunately it is not possible to turn off the “microphone off” icon as this is made by design, you can only turn off the all OSD mode with the following command:
xConfiguration Video OSD Mode : on/off
It is only possible to turn off the following Icon: (no need to mentioned OSD InputMethod Cyrillic & OSD LoginRequired)
OSD TodaysBookings :
xConfiguration Video OSD TodaysBookings: Off
OSD MyContactsExpanded :
xConfiguration Video OSD MyContactsExpanded: Off
