Disable Automatic IR Bed Calibration

Hi,

I would like to know if there is the option to disable the automatic ir bed calibration that will be done before every print.

My problem is that I broke the original Robo R2 plane sheet, and I can't find it in Europe. From this site 140$ of shipment for 15$ product, is not affordable. I have bought a similar sheet on Amazon, but it has a white design on top as showed in attached image:



When the print start, the IR bed calibration system misinterprets the white drawing in the middle, mistakenly believing that the plane is wrong, and leveling it badly automatically, with the result that once in the middle, it begins to print in a vacuum.

So, there is an option to do manual bed calibration and deactivate the automatic calibration system?

Thank you,
Fabio
