You can always download the h.265 spec from here:

and check the level limits for a certain level. Then configure all relevant parameters of your encoder to match a specific level and set that level at the encoder so no magic things that are not wanted happen. |
That said, the default levels in HEVC are pretty sane for any given height * width * fps, and using the lowest content-compatible level maximizes decoder compatibility. x265 does a good job at automatically picking the optimal level for your content, and I only override it in rare and peculiar circumstances.
For reasonably slow presets and a broad range of content, the max bitrate/ref frames/ecetera of the default profile is almost always sufficient for excellent quality.
