How do you think a Pentax AF 540 FGZ II that is attached to a V6II receiver releases an HSS burst, if it "thinks" it is not connected to any particular system?
Enticing an HSS burst (i.e., not a regular pulse) from a flash at a certain power requires digital communication with a flash. Just look at the pin-layout for the Pentax flash hot-shoeand you'll notice that there are some pins for analogue TTL control, but only one digital pin. So any control must be achieved by "talking" the digital language of the flash.
In other words, your assumption is incorrect. A V6II receiver (transceiver in Rx mode) will trick an attached flash to believe that the flash is communicating with a camera of the system the flash supports. Just as a V6II transmitter (transceiver in Tx) mode, tricks a camera to believe that it is communicating with a system-dedicated flash.
There is absolutely no other way the whole system can work as it does (as it does effectively translate between different HSS systems, e.g., Pentax camera -> Nikon HSS flash).

If you are considering the case were a dedicated (in this case "Phottix") trigger exists, the Indra 500 does not need to be tricked at all. It communicates with its native trigger; no trickery required.
The challenge is only to make the Phottix trigger believe it is talking to a camera system it supports. Chances are that the V6II can do this, unless the Phottix trigger for some reason requires some parts of the system protocol that isn't strictly required to perform HSS and the V6II does not support it. There are many examples where native triggers from Profoto, Godox, or Jinbei, etc. work on a V6II just fine.
There is another scenario for studio strobes, of course, where no native trigger is present. In this case the only chance to still get HSS is
- the strobe has an ISO hot-shoe connector and supports one of the V6II-supported flash systems (yes, this exists )
- the strobe can be put into HSS mode manually. Godox strobes/flashes have this ability.
- instead of HSS the next best thing, HyperSync, is used. In this case, the strobe just needs the ability to put out pulses longer than ~1/125s, or so. Only certain power levels, for which this condition is met, will then be available.
