Windows 10: I can hit tab to autocomplete words and phrases in Windows 11?

Edit metadata autocomplete list for pictures/music files

Disable Autocomplete

I am using a PDA/scanner that has Windows Mobile 6.5 installed. The autocomplete feature is interfering with my scans in Excel. Is there a way to disable this feature? The PDA is by Handheld. I use Excel mobile to display the scan of the barcode.
