Delay in loading Revolution Slider

Hi,
I’m using “Nitropack” on a website with “Revolution Slider”. When I enable Nitropack, the slider is not loading for some time and after a delay, the slider appears which causes a layout shift. I tried excluding the js and CSS files from the Rev-slide plugin using the settings in the Nitropack dashboard but, it didn’t work. Could you please help me to figure out this? I’ve also tried switching to the ‘Strong’ mode.
Thanks in advance.!
