Is there any way to lock specific anchor points?

I'm wondering if we could help you more if we knew more about what you'd like to achieve.  For instance, you use multiple shape layers in a smart object.  You can have multi-coloured vector objects that way as well.  You could also lock one of the shape layers inside the Smart Object, and edit thge other(s).  This sort of amounts to locking part of a shape.

If this an object you might want to use again, then dfrag it to a CC Library.  That makes them instantly available, and sortable by context / client etc.

I love that you can view a library in a web browser, and sort by type.  You can also share content keeping it as a vector object.

If you have some or all of the points in a path selected, you can de-select specific points by Shift-clicking on them with the Direct Selection tool, which would act like locking them.

You can't lock an anchor point, but if you are using the direct selection tool, instead of the selection tool, you can select all but the point that you don't want affected so in a sense locking it as you make your other manipulations. What are you trying to do?

Hi, from what I know, there is not this possibility. You can lock the whole layer, so the point inside that layer but not the single points.
