FATFS anti-tamp pin fixed?

I'm working on a project that involves using FATFS and I was curious if I had to use the specified anti-tamp pin that gets shown. I declare other input GPIO, but only PC13 shows up as PC13-ANTI_TAMP

What project? What pin selection?

The MicroSD Card sockets typically have a Card Detect pin, frequently closure to ground, that you can connect to ANY GPIO, and either Poll or use as an EXTI source.

More or less answers my question.

As to the project, it's kind of multi-step. I haven't worked with microSD or I2S before, so I wanted to start relatively simple and make an mp3 or wav player, with a MAX98357A I2S amplifier. Once I have my bearings with playing audio stored on a microSD through an I2S-based amplifier, I'm planning to make an audio mixer of sorts; playing multiple audio files at once, each with its own volume
