I have a click tracker tag which is something like
http://ad.doubleclick.net/ddm/clk/27406XXXX;10700XXXX;v?https://www.XYZ.com/
My question is if I change/update the click-through URL in the tag like
http://ad.doubleclick.net/ddm/clk/27406XXXX;10700XXXX;v?https://www.ABC.com/
will it still track the click in the same way as it was working before updating the click-through URL?
Yes. Static click trackers track based on everything before the query string, and then use the URL to inform the redirect.
