I am looking at https://ark.intel.com/content/www/us/en/ark/products/192990/intel-core-i9-9980hk-processor-16m-cache-up-to-5-00-ghz.html -> Has SMT https://ark.intel.com/content/www/us/en/ark/products/191047/intel-core-i7-9850h-processor-12m-cache-up-to-4-60-ghz.html -> Has SMT https://ark.intel.com/content/www/us/en/ark/products/191051/intel-core-i5-9600t-processor-9m-cache-up-to-3-90-ghz.html -> Doesn't have SMT https://ark.intel.com/content/www/us/en/ark/products/191126/intel-core-i3-9350kf-processor-8m-cache-up-to-4-60-ghz.html -> Doesn't have SMT (I just picked the first one in each list, so obviously I haven't looked deeper into it).
