I am using DPDK 20.11 and when I initialize the qat device, I find that both sym qat pmd and asym qat pmd are always initialized; however, in DPDK 19.02, I just need to specify the macro CONFIG_RTE_LIBRTE_PMD_QAT_SYM=Y to initialize sym qat pmd only. 

After I checked the documentation, I didn't find any clear solution.

So I would like to know if there is any way to initialize sym qat pmd only in DPDK version 20.11.
