How can I set the property of a hidden checkbox?

I have a checkbox that I'm trying to set, but it's not visible on the screen. I've tried the call object method and setting it through a script, but I still get the same error: "There was an attempt to perform an action at point (6, 6) which is transparent or out of the window bounds."

Aliases.browser.pageMxMerchantDashboard.panelPpsContainer.checkboxLast4DigitsOfCardNumber.ClickChecked(false)

Any ideas on how to set this checkbox?
