This is self-study. There is no need to study it as a specialized subject. The theory is easy to understand. The key is practical experience.
If you have the opportunity to participate in a training class, the training class usually only lasts for a few days. If you don’t have a foundation, you won’t gain much from studying for a few days! So I suggest you study on your own first, and then look for relevant training classes based on the faction you study. To avoid confusion, for example, if you study by yourself from the Xuan Kong sect, but the training class you attend is from the Bazhai sect, then it will be meaningless!
My suggestion: learn Xuankong Feng Shui, collect some relevant materials to study by yourself, and then participate in training when you are familiar with the basics.
