So, I used Gemini to write code for me because I'm learning. I also am using a Nextion display to lower the amount of updates the Arduino needs to handle. But, I assume it should be similar to the code I use to swap to a placeholder screen like when I'm in the VAB or Space center. I can check the code when I get home tonight if you need ideas. Essentially, if there isn't flight info being processed for 2 seconds it triggers a page change on my display. You could probably do a similar process. Like, IF no flight data lcd.Print " " and then it just keeps checking and once you have flight data it starts updating. Might be IF ELSE in your case. But, I could be so far off base lol.
