Hello everyone, I would like to make a pcb with a serpentine that acts as a heater to ensure a constant temperature at imu. The serpentine would be placed in the intermediate layers of the PCB. Is it possible to make this? How can I act to reduce the noise?

Of course it is possible to make this.

But I do not understand your 'noise' question.
Or are you talking about thermal noise? If so, you do not want to heat it.

With "noise" i by noise i mean electromagnetic noise. is it possible that the presence of the serpentine can increase the presence of electromagnetic noise on the various signals?

Of course it will increase the possibility of EMI issues. Both emission and immunity. You are creating an antenna.
However, if you do it right, there is no problem.

Carl made some videos about heating PCB, for example this one, but he has more: https://youtu.be/r0csHZveVvY?si=Ua6WSd3P_rRHBmwA
