429 Too Many Requests – ADD TO CART PROBLEM

Hello I have serious problem that is hurting my business.

My problem is AJAX Add to cart and too many 429 requests. If i spamm add to cart it will fill it with admin ajax requests and it will not add items to the cart but instead show 429 and unlimitedly spinn it. If person is logged in this problem goes away but if person is guest there is so much that my namecheap hosting will take.

Can you please go into my admin page and fix this issue for me? What I would like to achieve is users not getting this issue with many 439 requests, but if i disable AJAX in single product page then i will have caching issues with adding products to cart so AJAX looks like MUST here. Can you help me please?

Basically i want to be able to spamm add to cart without getting too much 429 requests , disable cart fragments or whatever its needed. I want to lock add to cart button until item gets added to cart so non logged in users can add many items to cart without getting kicked from website.
