I have the 2020 F-150 with a 5.0 and it burns a lot of oil. This is a known problem with the 2018-2020 F-150 5.0. Is there something I can put in my oil to slow this down? It is from the high intake manifold vacuum during deceleration, which pulls oil past the piston rings. This was a TSB by Ford that I am not able to use now since I bought it used and it was never done.

How do you know you can't access a TSB anymore? Did you check? If you pay the dealer for maybe an hour's worth of labor to update the truck's ECU, you should be able to access it. You don't need to be the original owner to gain access to a TSB; it's only when you've had the car beyond the warranty period that the dealer may require a fee to work on it.
@justin-shepherd it is well past the warranty period. Just trying to see if there is anything that can be done. The TSB didn’t really fix the issue anyhow and all they did was a reprogram and add a dip stick that shows 2 qts low and not 1 qt low. The most common fix is to replace the engine,, trying to avoid that.

Did you have the TSB done, or not? You posted in your first post that that you were unable to access the TSB. You can. The dealer isn't going to fix stuff for free unless it's a "goodwill repair" when the vehicle is out of warranty, though, and you really shouldn't expect Ford to care/ cover it. It hasn't been Ford's style to care for years.
Ford's track record has been "Ford doesn't care" for at least the past 11 years. As an example, Ford's engineers knew the PowerShift dual-clutch automatic transmissions that were being put in Ford's Fiestas and Focuses were defective, and they didn't care. Ford was sued by several class-actions and the class-actions won. Ford didn't care. Ford paid out and they discontinued both the Fiesta and Focus. Now, quality on their supposed "flagship truck", the F-150, has been having all sorts of issues and Ford still doesn't care.
In case you were wondering, your catalytic converter isn't designed with the intention of burning excessive amounts of oil. The catalytic converters will eventually clog up and both of them will easily cost $1500-$2000 to replace.
The most common fix is to replace the engine, trying to avoid that.
That may actually be your best bet, but those trucks also have the notoriously poor-quality GM-Ford 10-speed automatics, too. The engineering culture at Ford has been the moral equivalent of Beavis and Butthead with half-baked recall after recall for years.
