Bulk Delete of Spam Form Entries?

I have about 25,000 spam entries on a donation form - someone used my form to clean credit cards and charge small amounts on Stripe via my form. Even though I have integrated Cloudflare Turnstile. Anyway, now I have the task of doing 250 x 100 bulk deletes. It will take me hours since my internet connection is slow. Is there any way to do more than 1090 entry deletions at a time? Has anyone done it via cPanel and could give me instructions, if that the only way?
