set showTooltipMarker for single line

[L-x-C]

• [x] I have searched the issues of this repository and believe that this is not a duplicate.

What problem does this feature solve?

like this example https://antv-f2.gitee.io/zh/examples/line/multiple#series how to set the blue line showTooltipMarker: false while others true?

What does the proposed API look like?

showTooltipMarker(type) {
  return boolean
}

onShow: (obj) => { // 只显示一条线的marker return (obj.tooltipMarkerCfg.items = obj.tooltipMarkerCfg.items.slice(0, 1)); },

如果还有柱状图，要显示柱状图的提示背景，隐藏线图的marker，有没有办法做到？
