Yes, there is a form to request voluntary withholding from your Social Security Benefits. It is titled W4-V (Voluntary Withholding Request) and can be obtained from your local Social Security office or via the IRS website. https://www.irs.gov/forms-pubs/about-form-w-4-v
Unlike the W4 for payroll, you will only be able to choose a certain percentage of federal tax to be withheld. Turbo Tax offers a Tax Calculator (https://turbotax.intuit.com/tax-tools/) which will help you determine the correct percentage.
