-- setDefaultEncoding(PreferredEncoding encoding);
-  - Set the default encoding to select EVEX or VEX.
-  - The default value is EvexEncoding.
-  - This function affects only an instruction that has a PreferredEncoding argument such as vpdpbusd.
+- `setDefaultEncoding(PreferredEncoding vnniEnc = EvexEncoding, PreferredEncoding mpsadbwEnc = VexEncoding)`
+  - 1st argument. Set the default encoding to select EVEX or VEX for VNNI
+    - The default value is EvexEncoding (AVX512_VNNI).
+    - encoded as AVX-VNNI if VexEncoding is set.
+    - This parameter affects to vpdpbusd, vpdpbusds, vpdpwssd, vpdpwssds.
+  - 2nd argument. Set the default encoding to select EVEX or VEX for vmpsadbw
+    - The default value is VexEncoding (AVX/AVX2).
+    - encoded as AVX10.2 if EvexEncoding is set.
+    - This parameter affects to vmpsadbw.
