the dubious was
to be obliged to use the pins in the same column 3.3V
I don’t think I understand what you mean. To clarify, if you look at the picture you attached, OSPi occupies these pins:
(first 8 pins on the 3.3V column): 1, 3, 5, 7, 9 (Ground), 11, 13, 15 (these are pin numbers, not GPIO names)
(first 5 pins on the 5V column): 2, 4, 6, 8, 10
So these pins should not be used for connecting to your temperature sensor. You can use any other pin.
