change possible nodes of cluster role

Hi,

I have a 2 node windows failover cluster on windows server 2012r2 (NOT a hyperv cluster).

I am interested in changing a specific role to only be able to run on a specific node (I know that in a 2 node cluster this might not make a lot of sense but it is suppose to be a temporary thing)

however, using the GUI I am only able to view and change the preferred nodes and I interested in changing the possible nodes. strangely, I was unable to find a answer that worked on google. 

anyone able to assist me please? (GUI or\and powershell are both good options)
