Like you alluded to, one of the only customization options when it comes to altering the order quantity buttons is by enabling the Hide Account Info & Number pad setting which will change the display of the DOM. You can activate this by right-clicking within the black, blank space of the DOM as shown below:
That being said, do you typically use the same order quantity for every trade? Or do you switch it up?

This can be done by selecting the order quantity of your choice at the top right and then selecting the Set Def button. Whether or not the order quantity buttons is hidden, whenever you place an order, your order quantity will default to whatever you have previously chosen. Once you have a default order quantity set, you can hide those buttons again:

You can either right clicking a working order to change the qty/cancel it (this still takes two clicks) or you can use the Cncl All & Fltn button at the bottom of the DOM (which will only take one click, but cancel all orders at once).
An alternative option for canceling orders with one click is to have the recent orders window open. Within this window, you simply need to click on the red X once to cancel your working orders as shown below:
