Internal screen automatic brightness issue

My laptop Dell latitude 7285 got an Intel HD Grapics 615 and seems there is no ambient light sensor in the BIOS menu.
After a newly set up I found that screen backlight always gradually rise to max brightness.  Change the value in ACPI or simply slide the brightness in Gnome interface both available, but in the end system will tune the backlight to highest automaticly.
Is there any way to disable the automatic-brightness? I'm not sure what kinda information you guys need but this issue not always appear on every distro.
