Will modem inhibition truly release MBIM port ?

I am implementing a new firmware update mechanism with fwupd and libmbim
for new 5G modules. This new update mechanism has to use mbim port directly
(The mbim port cannot be opened with the proxy flag and cannot be accessed
by others during update.). I found that even if a modem is inhibited, its
mbim port still couldn't be accessed without the proxy flag. I checked the
log of modemmanager during inhibition. I saw the mbim port closed(but with
some transaction time out) and the modem disabled. When the mbim modem was
inhibited, I expected its mbim port could be accessed by others without the
proxy flag but it was still required. Would you have any advice on this ?
Is it possible to release mbim port when a mbim modem is inhibited ?
