One way to turn off the warning for delete-non-virtual-dtor is to use a pragma statement. For example, the following code disables the warning for MSVC compiler:

#pragma warning(disable: 4265)

class MyBaseClass
{
protected:
    ~MyBaseClass() {} // protected non-virtual destructor
};

#pragma warning(default: 4265)

This will suppress the warning for delete-non-virtual-dtor specifically for the MyBaseClass destructor. However, it is recommended to consider using a virtual destructor instead of a protected non-virtual destructor to avoid potential issues with object deletion in the future.
