Found this Review Tech site that mentions mainly Nvidia Passive GPU cards but does mention one AMD Passive GPU card RX460 but not sure if it will be strong enough for your use. It still is supported by AMD with Driver updates: Best Passively Cooled Graphics Card for Silent PC in 2020
Seems like the RX 460 4 GB Passive GPU card is sold in Asian markets only from what I read.

If a budget is of no concern for you, AMD has Professional GPU cards that use Passive cooling, but generally are not cheap.
Here is a list of all of AMD Professional GPU cards: https://www.amd.com/en/partner/professional-graphics-specifications https://www.amd.com/en/partner/professional-graphics-specifications
