Touch probe help

Yes and no.

A probe which involves X or Y needs to be done w/ a tool which has suitable geometry, and if using a v1, or making a probe w/ a v2 which doesn’t involve the center hole.

If probing for Z only, then tool geometry is immaterial assuming the tip of the endmill is where the cut should be measured from, so one may probe for Z only w/ pretty much any tool (but a BitSetter will be kinder to a delicate endmill should one not be able to probe at the unsupported corner of the BitZero).
