It is not possible.

Whenever a default bearer is released, corresponding dedicated bearers are also removed.

You cannot establish Dedicated Bearer(s) without Default Bearer, although you can have few Default ones without single Dedicated one.

The default bearer provides the UE with IP connectivity and the same IP address (es) are to be used by dedicated bearer(s).

So release of default bearer triggers release of all associated dedicated bearer(s) else UE may be without IP.

Under what scenario(s) is the UE-initiated dedicated bearer request implemented? This is discussed at 3GPP TS 24.301 at section 6.5.3 and 3GPP TS 23.401 at section 5.4.5. I understand that the UE can initiate a dedicated bearer with specific QoS, but am unsure when this occurs as a practical matter. If there were specific applications that required the UE to request a dedicated bearer, that would be helpful to know.
