Release DOF of beam in Abaqus/Explicit

Hello everybody,
I am trying to model a plate (shell elements) supported on rubber bearings and columns (beam elements) and I would like to know how to release rotational degrees of freedom at one or both ends of a beam element in Abaqus/Explicit.
Unfortunately, the keyword *RELEASE only works in Abaqus/Standard.
Thanks in advance for your kind help. Regards,
