First all R7 Series GPUs are not supported with AMD Driver updates. The last update is from 06/2021.
Second the R7-430 seems to be a HP OEM GPU card. So you will need to go to the manufacturer or HP to get drivers.
Here is HP last AMD Driver for the R7-430 from 2017: https://support.hp.com/ie-en/document/c05533252
Found this 08/2021 HP AMD Driver for all R5/R7 4xx GPU cards from here: https://support.hp.com/us-en/drivers/selfservice/swdetails/hp-elitedesk-800-g4-small-form-factor-pc/...
