I was told by the guy at hone depot that I couldn’t just use an adaptor because it will burn the Tesla cord instantly and it needs some type of power modulator like “juice box”.
You need the correct adapter from tesla, not something from home depot. As long as you dont plan on plugging and unplugging from your "dryer" outlet all the time, you just need the correct adapter from tesla to plug into the dryer outlet.

Your HD guy was pointing out that the EVSE has to not pull more current than your circuit can bear.
E.g., a 14-50r to 10-30p adapter would indeed have that issue.
The Tesla sold adapter sets the EVSE to match your circuit.
Notice the difference: it is not a generic plug to plug adapter, it is a Tesla specific EVSE plug

Just get the 10-30 adapter from Tesla from the link listed, and call it a day. The home depot guy is probably referring to installing an actual EV charger, which isn't needed if all you wanted to do is to use the included charger that comes with your car.
Nice. Yeah the guy said if I do that it would melt the cord instantly. I’ll get the adapter!
That's a 6-30 outlet, Tesla doesn't sell a 6-30 adapter for the NEMA adapter, but you can get this: NEMA 6-30 Adapter for Tesla Model S/X/3/Y Gen 2 – EVSE Adapters
You don't have to upgrade to 14-50 as 30 amps from the 6-30 outlet should be more than enough for normal charging (about 22 miles/hour charging on 30amps).
That’s a 10-30 plug. At 240v / 25 amps, it will charge at just above 6 kw, which is plenty for routine daily charging for a commute, but might be frustrating if you need to quickly charge from empty to full. A NEMA 14-50 will charge at 40 amps, or about 60% quicker. A Tesla (or juice box or Chargepoint) wall charger will charge at twice the speed of your existing outlet. How much does speed matter to you? You can always sell the 10-30 adapter if you decide to upgrade.
You’re totally right - my bad. Thanks for the correction.
No worries, too many damn plug variations in the US anyway, 15-xx, 6-xx, 10-xx, 14-xx, etc...
You've gotten some great information already, so I don't have much to add, other than to say that I'd do a very thorough job of inspecting the outlet before using it. Turn off the associated breaker, and then verify that there is no electricity at the outlet. Open it up, and check to make sure that the wires are securely and appropriately attached to the receptacle housing. Look for any signs of overheating at the wire attachment points. Also plug in your charging cord and make sure that it makes good, solid contact and isn't loose.
Bad connections cause increased resistance, which causes a lot of heat.
Thanks for the help! I will start with that adapter and go from there. I will also inspect the outlet first. Great advise. I have a super charger 3 minutes away too so I am lucky in that regard!

For the 14-50 you'll need a new 50 amp breaker (and an open slot in the breaker box)
new 6-3 wire and a new 14-50 outlet. You can't reuse any of that dryer circuit, the wires are too thin.
Also for standard range plus, it's limited to 32A. So if that's your car, you can't fully take advantage of the 40A charging with the 14-50.

That's a TT-30. Tesla doesn't make an adapter for it, but EVSE Adapters does. It's gonna be a pretty slow charge, though... about 10 miles range per hour charging. TT-30 Adapter for Tesla Model S/X/3/Y Gen 2 – EVSE Adapters
