The orange angle grinder (4.5") from harbor freight is $18 with the coupon
(or $20 on sale right now). A segmented diamond blade for said angle
grinder is fifteen bucks.
The problem is that cement backer board releases a lot of silicone dust when
it is cut by a power tool, so you would need to isolate the work area, wear
a respirator (safety goggles, hearing protection, old colthes) and clean up
***thoroughly***.

Hi Jon,
The panel is NOT a cement backer board. Its face has shiny white
squares and the back is tempered hardboard.

Oh okay, I gotcha, that laminated stuff. I'd use a straightedge and several
new razor blades in a good razor blade knife. Hold the straightedge
securely and keep cutting passes (away from your fingers) until you make it
through. Flip the blades and replace them frequently - they are a
consumable item. It's gonna take a lot of passes, so be patient.

Here in Canada it's known as barker board. Might want to take a look at
their site for tips:

that would be silicon, not silicone. they're way different.
