i have 10 node cluster, and i want to do the following quorum setup:

1,2,3,4,5,6,7,8,9,10

51% of all nodes and at least one of (4,5,6)


how it can be done?

AFAIK you cannot set certain hosts to present to have quorum. The majority will have the quorum. Because of this, it is also recommended to have an odd number of hosts in a cluster so that there cannot be one half of the cluster online. To avoid this you can add a small external "device" that adds one more vote to the cluster to have an odd number of votes.
