Risk based pricing is based on the credit risk of the individual borrowers.
If you mean can you have separate pricing for different counties, that is a totally separate issue.
If you do, it should be well documented as to the reasons, i.e., documented competitive pressures, etc., especially if the demographics between the counties are different. A higher price in a county with a higher minority population or customer base might lead to a disparate impact.
