IKEA Maximera cabinet - space behind it?

Dear forum,

maybe someone here can quickly help me regarding the Maximera cabinet: We are getting our Ikea kitchen on Monday, but we have the problem that we couldn't remove an old dishwasher water tap (for various reasons), which is exactly where a drawer cabinet is planned. With a "normal" cabinet, the option would be to adjust the Pax back panel, but with drawers? Does anyone know how much space is there? Or does anyone have an idea how to solve the problem? (I fear it is not solvable)

Thank you very much for your answers.

Shut off the water, unscrew the water tap from the wall, screw in the plug, done.

Install a small drawer at this spot and cut out the back panel.

Just measured, about 15 cm of space to the wall.

In case of doubt, use the 37 drawers as specified by firecrackers, or adjust the drawer. We did this under the sink.
