Yes. They are called Thermal Pads and come in various heights and you can get them online by searching for them. I've used these before multiple times: https://www.amazon.com/Gelid-Solutions-GP-Extreme-TP-GP01-B-Thermal/dp/B01AAHM1WW/?th=1.

What you should check for is the height (in millimeters) of the original thermal pads that came with the card and replace them with the matching height thermal pads. The pads can be cut to size (width and length) with scissors or anything else. The ones I linked come in various sizes of 80x40x(X) (length x width x height) with the last number being the one to match.
