Will using Google Tag Manager double send data from my Facebook Pixel?

Hi, We know that if we install the Facebook sales channel to my store, it automatically installs FB Pixel and Conversion API to the store. But I want to manage and add all the trackers and tags from Google Tag Manager to make sure I do not mess up with the base code and keeping things neat. But If I am to use GTM, I need to connect my existing FB Pixel to GTM. My question is if I install the same pixel with GTM that is already connected to the store via the FB Sales channel, will the pixel be sending the same data double times?
