Greetings,
Is there any possibility to move a single vertex on an edge (attached-please-find-image).
If yes how?
I am about to close holes in three 3d solid surface to make a one volume solid.
Thank you in advance.
PS
I have not found pertinent information on the web or help.
With SUBOBJSELECTINMODE= you can grab one or more vertices of a solid. But I doubt that you have a solid (a solid doesn't have gaps). And for surfaces this doesn't work.
Post your file please so we can do a closer look.

I have attached the file with the solid.
Opening your file I get a warning:

I don't know why the Properties say it would be a solid. It is not. The massprop command tells it has no mass and no other mass properties .
And also Solidedit->Check tells : "This object is not a valid ShapeManager solid".
In Autocaad you will have no luck to handle this file. Where is ist coming from? Maybe you can export the source in another (better suitable) format?
[EDIT]:
You can explode this "solids" to regions. But this regions don't wrap a closed volumen. A lot of information is missing in this file.

The uploaded "AC-Surface Base-EX_05_08A-3dP_03.dwg" (Polygonmesh) is a good startpoint to repair the model.
Theoretical (first read the end) you could do this:
1.) (optional): Move the 4 Polygonmeshes apart by a definded amount to have a better handling.
2.) For each of the meshes do this:
2a.) Explode the Mesh - you will get a lot of 3DFaces.
2b.) If necessary you can grab the endpoint(s) of a 3DFace and drag it to another position (using a suitable osnap). This is what you are looking for.
3. To check if you will get later a valid result:
3a.) Convert all 3DFaces to surfaces (CONVTOSURFACE command).
While testing in ACAD 2020 I got error messages, that some 3DFaces could not be converted (e.g.
9500 3DFaces should be converted, 200 could not, for any reason). Here you will find holes in the mesh. You have to fill this holes with manually drawn surfaces.
In ACAD 2021 I did not get such holes (but I didn't test the complete model).
3b.) Next I would (still for each of the meshes) try to union all the surfaces to one surface. While this I also got error messages (modelling operation error). You have to find which surface causes this error, delete it and create a new one.
4.) When all 4 polygonmeshes were successful convertet to 4 surfaces, you can move this surfaces back to their source position an check each edge where one surface touches its neighbor. If you find errors (overlapping, gaps, ...,) you have to repair this too.
5.) If all this is done successful you can combine all surfaces to a solid (convtosolid or sculpt).
But I think, you never will reach this point. The given modell includes too much problems (modelling errors, corrupt faces, ...). I can't belive that someone will have so much time and patience and endurance to finish this job.
Maybe another applikation is more tolerant and can do this job, In AutoCAD it is theoretical doable, but practical IMO not.
sorry, I can not help.
