here some guidance that you can try. 

Install a Geolocation Tool:

• Use a geolocation library (such as geoip2) to map IP addresses to geographic locations. Alternatively, consider using a third-party API like ipstack or ipinfo for this purpose.

Create a Custom Odoo Module:

• Develop a custom Odoo module that detects a user’s location based on their IP address. This module should make the location data accessible to your website templates.

Modify Website Templates:

• Use the location data in your website templates to conditionally show or hide elements. For instance, display specific phone numbers or content based on the user's detected province or region.
