Is a nft mintint smart contract that doesnt have a fixed price per nft possible?

I want to have a price per nft that is minted, so for example i want that nft to cost 10 dollars. So less than 10 polygon (matic). I want to be able to use that smart contract basically forever, but what then if the price of 1 matic becomes 10 dollars the price for the nft's need to be 1 matic.

I understand that you cant alter a smart contract after its been deployed. But how can i do what i want. Like i need to be able to change the ft minting price if polygon ever becomes too expensive.

Also i understand i could make it so that people need to supply for example a stable coin pegged to like a dollar. So that way the price says the same. But I'd rather have it for just polygon matic as the price.

But is this possible without stable coins? Is there a way i can change the price per NFT? Or is there like a script that is able to do this in a smart contract or other ways?
