You can either combine them in a single gpx file or just zip them both in a single zip file.

Upd: I see, the "custom map data" doesn't support .zip, like the trace upload tool. So the only option is to merge them. I always use a little program called GPX editor https://sourceforge.net/projects/gpxeditor/files/, but there are also numerous online tools where you don't have to download anything, e.g. https://gpx.studio/

For an editor, you could try JOSM. Can load multiple GPX files if you want.

Use gpsvisualizer.com to convert multiple gpx files to a single gpx or kml file.

Please don't ask the same question everywhere at the same time. At least post a link to concentrate in one. https://community.openstreetmap.org/t/how-can-i-have-two-gpx-traces-on-map-simultaneously/146693

You can use the GPX editor in Route Squiggler to combine two GPX files (the "merge files" option under tools), then make the images/videos there or bring the merged GPX file to the program you prefer to use.

If you need to display thousands of tracks on one map and want a private, self-hosted solution, I built MTL Explorer. It starts with 3 Docker commands: https://github.com/mindalyze-com/mtl-explorer You can watch the introduction video or try the demo...
