To be eligible for Stripe's Chargeback Protection Program, payments need to be processed through Stripe's new Checkout page infrastructure.
For the Guesty Booking Website, Guesty's in-house checkout page is used, so payments made through Stripe are not eligible for the Chargeback Protection Program.
For booking channels, the checkout page is on the channel itself, so eligibility for the Chargeback Protection Program would need to be met by the channel, not Guesty.
