Hello,
To limit the number of variation circles (swatches) which you marked in red circle displayed on the shop grid, please adjust the following settings in Theme Settings:
1. Go to Theme Settings > Shop > Variable products.
2. Under “Grid swatch attribute to display”, select the attribute you want to show (e.g., Color).
3. Enable the “Limit swatches on grid” option and set a limit (for example, 4 or 5).

This will display only the first few swatches on the product card and replace the remaining ones with a “+X more” link, saving space on your shop grid.
Best Regards
