Here is the command which set the client to use two-time servers, if you want they have priority you can using 0x2 0x8.
w32tm /config /manualpeerlist:"ntpserver.contoso.com clock.adatum.com" /syncfromflags:manual /update
w32tm /config /manualpeerlist:"ntpserver.contoso.com,0x8 clock.adatum.com,0x2" /syncfromflags:manual /update
0x08 is for registry Announceflags means Automatic reliable time server
