1. A method for processing video data, comprising:
determining, for a conversion between a first video block of a video region of a first current picture of a video and a bitstream of the video, that at least one of one or more first coding tools is disabled for the first video block due to a first reference picture resampling being enabled, wherein whether the first reference picture resampling is enabled is based on at least one of a width or a height of the first current picture, wherein, when the first reference picture resampling for the first current picture is enabled, a first reference picture of the first current picture has a resolution different from a resolution of the first current picture, and wherein the one or more first coding tools comprise a bi-directional optical flow (BDOF) tool; and
performing the conversion based on the determining,
wherein whether a first syntax element is signaled in a picture header of the first current picture is determined according to one or more syntax elements in a sequence parameter set (SPS) that is associated with the video region, and wherein the first syntax element indicates whether one of the one or more first coding tools is disabled for the first current picture or not.
