It notes that you need to first have it enabled by PayPal.
Verified by an attempt to checkout with this enabled, and receive this error:
PayPal gateway has rejected request. Billing address request is not enabled for merchant (#11601: Request for billing address failed).
Paypal support: https://www.paypal.com/us/smarthelp/article/why-did-i-get-api-error-code-11601-ts2035
When reached out to Paypal support, they replied:
"As PayPal cannot enable the billing address, I would advise you to and disable the billing address request option in your settings."
Is there any solution to this issue?
