GPSR regulation and Woocommerce & Printify question

I'm not sure which forum to ask this question, forgive me if it's the wrong one. I'm about to set up my Woocommerce store & to integrate it with Printify. It's only a couple of days since I became aware of this GPSR, so I wanted to know from you experienced peeps, if it's possible via the admin, to prevent access to my site to Northern Ireland & EU customers only.
