1. A method for wireless communications at a user equipment (UE), comprising:
transmitting, to a base station, a capability message indicating a capability of the UE to perform envelope tracking using digital post distortion (DPoD), and further indicating an envelope tracking configuration to be used for transmission of an uplink message;
receiving, from the base station and based at least in part on the capability message, a request for the UE to activate the envelope tracking; and
transmitting, to the base station and based at least in part on the request, the uplink message in accordance with the envelope tracking configuration.
