disable request a quote for some variations of a product

Hello! we have variable products in our store. By default, there is an ‘Add to cart’ & ‘Eequest a quote’ button for all the variations of the product. I want that when users choose specific options/attributes, they should not see the ‘request a quote’ button or atleast it should be disabled and when they choose some other options, add to cart can be disabled and ‘request a quote’ can be enabled. As for some variations of our products, we cant be so sure about the final price and want that users should ‘request for a quote’ by filling in the form. For other variations, the price is fixed. Please let me know if this is possible with this plugin.
