You can do the polaris one click flash or use the paid version you can find it here:

https://mining-bios.eu/product/polaris-bios-editor-3-pro-pbe-3-pro-performance-timings/

But first read about it and make sure you know what you're doing, I personally like the paid version more, but it's your choice, check the site and read about it.

Hope it helps.
