Why am I unable to turn off advanced inventory in QuickBooks

I have recently decided not to use the Advanced Inventory feature anymore and Turn off Advanced Inventory in QuickBooks. But the worst part is that I didn't find any helpful information over the internet to do the same. I was on the call with the experts, and he said that once you enable the advanced inventory feature, you won't disable it. If you have any other suggestions, please share them with us because we have tried almost every possible suggestion, which keeps getting progressively worse.
