Hey,

You can redefine the field by inheriting the model and adding the param store=True but what you should be concerned about is that as soon as you make a computed field stored in the database then it stops re-computing the value on the fly, then you'll need to define a @api.depends param for the compute method to let the Odoo know based on the change in the value of which field the method needs to be triggered, just making the field stored will stop computing the correct value.

Thanks and Regards,
