not sure if it works in ectune but i have seen someone force the ecu to switch to the high cam map at a certain rpm on hondata for a non vtec car. Just looking at ectune's options, it might do it.
both of those options are possible. you can run high cam map only, or you can just set it up as VTEC and disable all errors and belnd the fuel and timing smoothly and it will work that way too.
