def task_func(hex_str):
    """
    Converts a hex string representation into actual bytes and records the frequency of each byte value.
    The function supports hex strings with or without '\\x' prefix.

    Parameters:
    - hex_str (str): The hex string (e.g., 'F3BE8080' or '\\xF3\\xBE\\x80\\x80').

    Returns:
    - tuple: A tuple containing a pandas DataFrame of byte frequencies with columns ['Byte Value', 'Frequency']
             and a matplotlib Axes object for the plot with 'Byte Value' as the X-axis and 'Frequency' as the Y-axis.

    Raises:
    - ValueError: If 'hex_str' is not a valid hex string.

    Requirements:
    - binascii
    - numpy
    - matplotlib.pyplot
    - pandas

    Example:
    >>> df, ax = task_func('F3BE8080')
    >>> print(df)
       Byte Value  Frequency
    0         128          2
    1         190          1
    2         243          1
    >>> plt.show()

instruct prompt

Converts a hex string representation into actual bytes and records the frequency of each byte value. The function supports hex strings with or without '\\x' prefix.
The function should raise the exception for: ValueError: If 'hex_str' is not a valid hex string.
The function should output with:
    tuple: A tuple containing a pandas DataFrame of byte frequencies with columns ['Byte Value', 'Frequency']
    and a matplotlib Axes object for the plot with 'Byte Value' as the X-axis and 'Frequency' as the Y-axis.
