I'm preparing some PRs to add our u-blox nRF52 and nRF53 EVK boards to Zephyr. I'd like to run twister locally and seem to have things working. I'm running out of drive space due to the size of the twister output. What's the best way to either limit what gets tested (i.e. don't need other than nRF5x), or what size drive should I allocate to my VM?
