Have you repotted this tree before?
I ask because I am wondering if you know what is happening under the soil line?
I would dig down to see where the major roots come of the trunk. This tree may have more trunk under the soil? Depending on what you find, a ground layer may be an option?
Finding where the main roots emerge on the trunk below the soil line will help you decide if you need a change in angle/inclination of the trunk line for possible future design and direction etc, wether or not to remove the above ground roots, if you need a ground layer, at what height the tree could be trunk chopped at (if you wish to reduce the height?).
If there is no major portion of trunk below the soil, the tree could still benefit from change in trunk line, trunk chop, ground layer, removal of above ground roots etc.

Let us know what you choose to do. Nice bark on this tree
Cheers, Dario.
