Simple answer is no, it is not a possible option.
There is only one instance I have heard of where two males did live together without fighting. They were brothers who were raised together since hatching and there was no female dragon owned or anywhere near the males. However I consider this a very rare exception and considering how fast and deadly dragons can be if they decide they are not compatible, even with male/female or female/female groups, the damage one can do to another in a short period of time, makes it not worth risking putting two males together.
The only other way I can see two males being kept in the same cage without much chance of serious fighting, is if the cage they are in is HUGE..and I don't mean 5'x3' huge...I mean more than twice the size of the minimum recommended size for a single adult dragon, or more...say more like 8'x4'x2' (lxwxh) with plenty of basking areas a good distance from each other and visual barriers...this way the males can keep out of each other's territories...but even then, there is always the chance of a particularly aggressive male still chasing down the other to doing it harm.
As most people don't have a room free that can be converted into a dragon cage for just two dragons...far more practical to have two separate cages, one for each male.
