Hi @Arabdevs8,
Considering AddReplaceTexture is an experimental native, my assumption would unfortunately be: you can’t.
However, that’s not definite, perhaps someone could shed some light on this and prove me wrong (hopefully!) 
Although this may not be exactly what you’re looking to achieve, I think you should take a look at this resource and research more about DUIs.
The resource I’ve linked essentially does what you’re looking to do but displays videos instead of replacing textures. Perhaps that’s a concept you could implement? So create a DUI in front of each clipboard and display a unique texture/image instead of a video?
