Is there a way to hide all markers except for a specific series?

[MarByteBeep]

I have a situation in which I show hundreds of series in a form of spaghetti, but want to have a clear trendline running through it.

Using the following options:

...
	stroke: {
		width: [6],
	},
	tooltip: {
		enabledOnSeries: [0],
	},

This results in the following graph:

I can ensure the tooltip only shows series[0], which is the trendline. However, still all markers of the other lines are displayed.

I've tried changing the marker sizes by setting all marker sizes to 0, except for the first one (which is the trendline). But that resulted in a very, very slow graph and a non-functioning tooltip.

I also tried fiddling around with the tooltip settings (such as shared and intersect). But the moment I set shared to false, no tooltip is shown at all.

How can I hide the markers of those grey series? Basically those series shouldn't have any interaction. They are just there for visual purposes. They're disabled otherwise.
