Can I run a ground wire to its own isolated grounding rod?

Hello, I just bought a new range and my 1963 house has a 3 wire receptacle. My instincts are telling me I shouldn’t just pigtail a 3 wire to the back of my oven, shove it in and call it a day. That’s what everyone around me is telling me to do.
My understanding of the old style 3 wire is that they have two hot wires and one neutral wire, with no ground. Instead of running a new ground wire all the way back to the ground bus in the panel, can I just simply run the new ground wire to its own isolated grounding rod?
Thanks for any help.

My friend any time you deal with a range or dryer you have to pull the old wiring out and crane the cable to a 4 wire instead of 3. Back in the old days they used the bare equipment ground for the neutral, which is not allowed anymore and has to be brought up to code

I never have cared for them, the best way is to abandon it and replace it with a proper 4-wire feed, but the exception to NEC article 250.140 does permit existing 3-wire installations to remain, if it is extended then a upgrade is required. The code changed no longer allowing 3-wire in new installations with the 1996 edition, do not run a ground wire to a rod, not likely to get enough resistance to clear a fault, which would means someone touching the appliance when a fault occurs would be shocked, plus code does not permit a rod to act as a equipment grounding conductor.
