magento2 – Change meta tile from uppercase to lowercase

Good evening community,
I ask for help from you, because I am not an expert programmer.
I would need to change all meta tiles from uppercase to lowercase. Example :
MY PRODUCT
in
My product.
I think it is already possible from the magento back end by going to the Shop-> Configuration-> Catalog-> Auto-Generation
enter image description hereproduct fields tab and add some attributes to the name field, but I have no idea which. So I’m waiting for someone more experienced than me to give me a hand. Greetings
