Is there a way to send keyframes on demand

I am using libx265 for a streaming application. Every time a frame in transit is somehow dropped the resulting decoded stream "greys out" until a new keyframe arrives. My understanding is this is due to the loss of information between keyframes.

My question is, if we are able to detect a lost frame, would it be feasible to request a keyframe from the encoder so that we can recover faster from the grey screen?

Thanks very much,
