Are you referring to the Multiple BSSID information element? (you really need to be specific about what you're asking because as per above because MBSSID is also just a generic term for an AP broadcasting multiple SSIDs).
If it's the element you're referring to then most older drivers (certainly pre-802.11ax) will either not recognise it or will not see the SSID at all. Even some earlier ax drivers won't work correctly. So best not to enable it if your WiFi must support anything but the very latest clients otherwise you're likely to disrupt clients.

Basically you're normally only going to see it on 6GHz where it's now mandatory so all clients should support it.
Note 9120 AP does not support the 6GHz band.

Hi
Multiple Basic Service Set Identifier (MBSSID) is not any special feature, it is just one AP propagating more then one SSID. The SSID is represented by an Mac Address to differentiate each other and actually is to that Mac address that clients connect.
When you say you are not able to enable MBSSID I understand you are not able to enable SSID at all.
Is this an autonomous AP or it is plugged to some WLC? Can you share the config here?

We are able to create SSID and the same is broadcasting as well , but may I know how can I test the MBSSID feature and also even though I created 2 SSID's unable to see MBSSID bit in sniffer capture.
whether cisco AP supports MBSSID feature or not how to check?
