Hello @MuniSIGGeopraia,
Typically the "Survey123 requires a base enterprise deployment" error message means that there isn't a hosting server configured with the ArcGIS Enterprise Portal.
Please use this link for reference regarding configuring a hosting server: https://enterprise.arcgis.com/en/portal/latest/administer/windows/configure-hosting-server-for-porta...
If you need assistance configuring the ArcGIS Enterprise base deployment I would suggest reaching out to Esri Technical Support and an Implementation analyst will be able to assist with the configuration.
Thank you,
Zach
