Apply 2020.refubs to 2024 Estimated Taxes?

Hello. I'm due a small refund for 2020 taxes that I'm finally getting around to filing. Can I apply the refund to 2024 Estimated Quarterly taxes instead of getting a refund?

On the 2020 Form 1040, the option given is to apply your overpayment (refund) to your 2021 estimated taxes.  Most likely the IRS would not apply your refund to your 2024 tax return.  The following image is from 2020 Form 1040.
