Duo SSO with OWA | Uninstall duo for OWA from Exchange Server

Hi community,
I working on configuring Duo SSO with OWA for enabling exchange mail client to 2FA when they sign in to OWA. we already install Duo for OWA in exchange server and user can sign in with 2FA, However, if I uninstall Duo for OWA from Exchange Server, does the user can sign in and authentication with Active Directory as normal without prompt for 2FA?
