1. A method of video decoding in a decoder, comprising:
determining, by a processor, a first syntax element for coding control in a first scope of coded video data in a bitstream, the first syntax element being associated with a second coding tool that is alternative to a first coding tool for Rice parameter derivation in a residual coding; and
in response to the first syntax element being a first value indicative of disabling of the second coding tool in the first scope, decoding, by the processor, the first scope of coded video data that includes one or more second scopes of coded video data without invoking the second coding tool.
