I wonder if it’s impossible… As you say, if you leave it blank, it gets filled with the default values, but you can fake it by typing a space in the field. The tag will still show up with no value. 
% ffmpeg -y -i "E:\ts_sample_with_metadata.ts" -c copy -program program_num=0x1111:st=0:st=1 -metadata:p:0 service_name=" " -metadata:p:0 service_provider=" "  "E:\ts_sample_without_metadata.ts"
