According to this, PA4 is used for calibration of IHRC.

Ahh! Thanks for the catch! Do you know about "the limit" of usage of this pin to other things "in circuit" ?

This is pure speculation on my end: so your as your circuit does not excessively load the pin, you should be alright.
Of course, this comes with a whole long list of caveats - for example, in my application, I have PA4 connected to a MOSFET controlling a small vibration motor. Trying to program and calibrate a PFS172 while the motor is connected results in failure, which I believe is caused by the power rail browning out.
I would strongly suggest that you test your intended circuit to confirm for yourself whether it'll work in your application.
