How can I accept both rvalue and lvalue non-const parameter type

I'm repeatedly running into the problem of accepting a non-const reference parameter, since it seems taking an rvalue parameter prevents accepting lvalues and vice versa. Here's an example

void read(File &file)// I want to modify file
{
    SomeClass someObject;
    file.readInto(&someObject);//readInto is a non-const method
    // do something with the data populated in someObject
}

But when I try to call read I have a problem if I try two different calling conventions

//this works just fine
File f1 = File::open("some_file_path");
read(f1);

// However this fails
read( File::open("some_file_path") );//because open returns an rvalue

The problem I have is if I change the parameter to a non-const rvalue than I can't pass the lvalue anymore. Am I doomed to always provide an override (or template) that takes the rvalue reference type and simply calls out to the lvalue override?
