A static method provides NO reference to an instance of its class (it is a class method) hence, no, you cannot call a non-static method inside a static one.

Of course you may either

Create an object of the class inside the static method and then call the non-static method using such an object.

or

Pass an instance of the class as static method parameter (and then, again, use such instance for invoking the non-static method).

Due to the vagueness of your question there can be many other ways (for instance, calling a non-static method of an object of a completely unrelated class).

Providing examples is left as an exercise.

Short answer: No.
You can't access the class instance from a static method of a class. Just think about: A static function does not know which instances do exist when called. It may be multiple or even none.

However, you can pass a reference to a class:

C#

class MyClass {
    void NonStaticFunc()
    {
        // Do something
    }
    
    static void StaticFunc(MyClass self)
    {
        self.NonStaticFunc();
    }
}

MyClass myclass;
myclass.NonStaticFunc();
MyClass.StaticFunc(myclass);

But that makes no sense when using it with instances of the own class. Non static functions are always called with the hidden this (C# Reference) | Microsoft Docs[^] reference.
