keyboard-shortcut or command-line-option to disable multiple Excel features temporarily

I need a Workbook stripped of all functionalities and features. When opened

1. a Window of 1 column 4 rows shows
2. End-User paste into 1 cell from Clipboard into 1 cell only
3. hit F9 to Calc
4. copy another cell into clipboard.
5. Close Workbook; other Workbooks will not be used when this Workbook is opened.

Similar to Microsoft Calculator App in shape & form but different function. Ideally, this Workbook can be configured for best performance sacrificing aethestics and features (e.g. Add-In, Ribbon, Proofing, Scroll-Bar)

Unfortunately, many features (i/c Add-Ins) I like to turn-off

1. affect all open Workbooks
2. no keyboard-shortcut to disable multipe features temporarily.
3. no command-line option to open another Xl instance with disabled features .
4. I understand VBA can temporarily do this but since my company restrict VBA, is there a Microsoft endorsed source-code for this? Alternatively, is there best practise?
