No, you can not block access to a port based on the service that will be generating the requests.

so you are not able to set up inbound rule to only allow certain applications to use SMB and block all other inbound request... ?
You would need to configure the outbound side to deny/block the applications from being able to access external resources.
Windows Firewall control panel, advanced settings is where you can define the rules.
You could restrict inbound requests to specific resources, but I do not think you can restrict access on a granular level i.e. workstations can not while server can.

What is it you want to do? you could export the default policy.
Adjust settings and see if you achieve what you want. If it does not work, restore/import the policy.

The closest way would be to create ACLs - list of IPs that can access mentioned host.
You'd need L7 firewall that would inspect packets for any application-specific traffic (provided the applications you want to block generate one).
