Matomo nonunique visits (disabled Cookies)

we have started using Matomo last year with setup that uses cookies. Since 1.1.2022 (GDPR update in the Czech republic) we changed our cookies setting to opt-out (cookies are not stored until user gives a consent). We haven’t changed Matomo settings yet.

I understand that this change impacts unique visits accurancy (since not all users have cookies in their browsers) but the change shouldn’t affect Nonqunie visits metric at all, right?

Thank you
