Need to Increase the job search radius up to 100 miles

We aim to expand the job search radius on our career site to make posted job requisitions visible to a broader audience. This expansion is expected to attract more applicants, ultimately increasing the number of hires. Our goal is to enhance the applicant flow to our job postings, as traditional sourcing and advertising methods are proving ineffective.
Is there any possibility to increase the search radius up to 100 miles in our current system or can this be achieved by integrating any 3rd party system?
