Properties can be changed at runtime. Whether this actually works is
entirely up to the particular element. GStreamer doesn't currently
have any mechanism to query whether a property can be modified in a
particular element state, though.

Most encoders do not let you modify the bitrate target at runtime -
but if you have an encoder that can do that, you should simply make
setting the property during encoding set the changed bitrate on the
underlying encoder properly.
