Hide grid label for players?

Hi, after searching briefly, I found no obvious way to achieve this: I want to display the grid labels on my hex grid map, because I intend to pre-generate encounters, and need a ref, because it's a big map, but it's very visually obnoxious so I'd like to hide it for the players. Is there a way to show the label only for the GM? To illustrate, here is what it looks like now, at an opacity setting that barely makes it legible (3 letters 2 numbers), so there is no way i can make it less opaque and still be able to read it quickly and efficiently. Looking forward to reading your answers. Thanks

In the mean time, I found a way around it: I made an image with my hex grid and numbers (which was not fun), that I exported as transparent png, upload it to the GM layer and pushed it backwards. It's also locked in place thanks to TheAaron Map-Lock script so that is does not get moved inadvertently. Not perfect, but it kinda works. Here is what my players see here is what I see Still curious if someone finds a better solution

I'm not sure if there is an easier way for that, the better option maybe is to have the columns and rows labeled in the edge and use the rule to pin point the point you want instead of having each hex labeled.
