This is a simple node disable func, useful if your graph is full of slow stuff:

def node_disabling(n_s_mode, n_class, switcher=False):

    """Simple node disable.

    Parameters

    ----------

    n_s_mode: str

        all -- search in all nodes

        sn  -- search in selected nodes

    n_class: str

        node class

    switcher: boolean

        False or 0 -- node enabled

        True or 1  -- node disabled

    Returns

    -------

    None

    """

    n_s = {n_s_mode == 'all': nuke.allNodes(),

           n_s_mode == 'sn': nuke.selectedNodes()}.get(True, 0)

    for i in n_s:

        if i.Class() == '{0}'.format(n_class):

            i.knob('disable').setValue(switcher)

    del n_s

# example

# node_disabling('all', 'Grade', 0)

Small code snippet for hotkey setup, extend hotkeys nested list with new items, usage:

['Draw/Grain',                         'Grain2',                          'Alt+I']

    ⇑                            ⇑                           ⇑

    Path                Node class and default values (optional)           Hotkey

# insert code snippet to menu.py

menu = nuke.menu('Nodes')  # if needed

hotkeys = [

           ['Filter/Blur', 'Blur, size 20 label "hello world"', 'B'],

           ['Draw/LightWrap', 'LightWrap', 'L'],

           ['Draw/Grain', 'Grain2', 'Alt+I']

           # ... and so on

          ]

def assign_hotkey(n_path, c_node, h_key):

    c_node_splitted = c_node.split(',')

    menu.addCommand(n_path, lambda: nuke.createNode(*c_node_splitted), h_key)

n_path_i = 0

c_node_i = 1

h_key_i = 2

for i in hotkeys:

    assign_hotkey(i[n_path_i], i[c_node_i], i[h_key_i])
