No Login without double opt in

Dear wordpress community,
i have a membershib website with learndash and woocommerce. Also i added the plugin germanized to ensure the gdpr compliance. Only now i have a problem with the double opt in registration. Users get their login info with the woocommerce mail and can login without pressing the “activate account” link. This way the germanized plugin deletes the login after 7 days because they didnt activate the account. Germanized also has the option to restrict the login and checkout when the user didnt activate the account. But this kills my conversion rate because the user has to create an account before ordering and not while ordering. does anyone have an idea how to restrict just the login and not the checkout?

Thanks for your answers!
