The phrase "a possible method of" is correct and usable in written English.
You can use it when discussing potential approaches or techniques for achieving a specific goal or solving a problem.
Example: "After reviewing the literature, we identified a possible method of improving the efficiency of the process."
Alternatives: "a potential approach to" or "an alternative technique for".
Finally, a possible method of production is proposed.
