Is it possible store some variables in Nextion nvram?

I need to store some settins of the display (for example users’s bright of display or some text variables like page.settings.txt=“my value”. Is it possible to store it in NVRAM and use them afrer power off of the display? Thank you.

For what is my knowledge, the nextion displays do not have NVRAM. However, Enhanced or Intelligent series have EEPROM on board and a usefull set of instructions to manage write and read data to and from that storage device.
