How can I use OCSP in kong gateway?

I want to use OCSP for public certification.
I use Loadbalancer infront of 3 kong-gateway.
The server for the certification exists outside, not the internal cluster.

I found this configuration about OCSP.

Can I simply set it to “cluster_ocsp=ON” for OCSP?
Can I use this only in the Enterprise mode?

I also found information that is an option set for OCSP between Kong DP and CP in Kong Hybride Mode.

I use three Kong-Gateway, not DP/CP settings.
