Facebook Pixel please help me

I created a Facebook pixel on my personal account, then I created another one linked to my shopify on Facebook Business Manager, since has the same feature of the old one in the personal account, how can I delete the Pixel I created on my personal account?

I don't see a way to do it on Facebook, I just replaced the code on Shopify with the new one but I want to delete on Facebook.

Anyone can help me please?

You don't have to delete it. Let it be. There is no any harm having it even if you don't use it. Some day you might need it.
