Usually equipment that has to be robust against this attack will have things like tamper switches that wipe storage keys and brick the device if it’s opened. I’d assume they also have software tripwires too if you manage to get the access you need (for instance if you drilled holes through the enclosure to access areas you needed without opening it - although if you really wanted to stop that you can do things like potting much of the board in epoxy that is extremely difficult to remove without destroying things).
