Stand-alone-LCD with buttons

Have apps I use that required the LCD buttons and screen. And don't want to use LGS as it conflicts with G-Hub Would like to have a stand-alone LCD with software that allows control of the buttons and screen allowing my apps to run. I hope you will be able to help. https://www.reddit.com/r/LogitechG/comments/ek5xcj/g19_keyboard_lcd_standalone/
