Remove battery icon on device

Nice to greet you. I would like to know if it is possible to remove the battery icon displayed on the device. I don't want the customer to see it because I am installing used equipment whose batteries are not at 100%. I have searched and found nothing in the settings. I would appreciate it if someone could help me with this. Regards.

You can use computed attributes to remove the battery level.

Thanks Anton, I added this attribute:

if (batteryLevel >= 0, 100, 100)

but the status doesn't change. Is it defined correctly?

I'm not familiar with this syntax. Where did you get it from? Please link to the documentation where you found it.

Sorry, I was given the wrong advice. But I managed to solve it with the calculated attribute of the battery level. I left the expression at 100 and the battery level went to 100%.
thanks.

You can also put null as an expression and it will be removed.

I tried it, and it works perfectly. Thank you!
