1. A method for video decoding in a decoder, comprising:
decoding prediction information of a current block in a current picture from a coded video bitstream, the prediction information being indicative of an inter prediction mode;
determining decoder-side motion vector refinement (DMVR) is enabled based on whether (i) weighted prediction is applied for luma components of the current block, (ii) weighted prediction is applied for chroma components of the current block, and (iii) a first prediction list utilization flag and a second prediction list utilization flag are equal to 1; and
reconstructing a sample in the current block based on whether the DMVR is determined as enabled, the DMVR being disabled responsive to at least one of (i) the weighted prediction being applied for the luma components of the current block and (ii) the weighted prediction being applied for the chroma components of the current block.
