Block update while setting multiple widgets

Question

Is it possible using Panel to temporarily disable the automatic linking of widgets while setting the values of multiple widgets?

The code below shows a simplified example of my situation, in reality I have much more widgets. The key issue is that I have a Select widget, that links to some pre-configured values in a dictionary, and on-change I want it to update all other widgets.

All of this works fine, except that when the first widget gets a new value using this, it instantly triggers a redraw of the entire plot before all other widgets are also updated. Not only gives this a unnecessary flickering effect (updating the plot n_widgets times instead of once), some intermediate values also cause the plot to show some "wild" results because the intermediate values cause unrealistic combinations.

dropdown_box = pn.widgets.Select(options=selection_options, name="selection")
slider1 = pn.widgets.FloatSlider(start=0, end=1, step=0.01, value=0.5, name="slider1")
slider2 = pn.widgets.FloatSlider(start=0, end=1, step=0.01, value=0.5, name="slider2")
slider3 = pn.widgets.FloatSlider(start=0, end=1, step=0.01, value=0.5, name="slider3")
slider4 = pn.widgets.FloatSlider(start=0, end=1, step=0.01, value=0.5, name="slider4")

@pn.depends(dropdown_box.param.value, watch=True)
def update_cfg(selection):

    val1, val2, val3, val4 = lookup_cfg[selection] # lookup_cfg

    # < some intermediate stuff >

    slider1.value = val1
    slider2.value = val2
    slider3.value = val3
    slider4.value = val4

my_plot = hv.DynamicMap(pn.bind(
    create_plot,
    param1=slider1, 
    param2=slider2, 
    param3=slider3, 
    param4=slider4,
    **plot_kwargs,
))

Even assigning all slider.value's on the same line still causes the widgets to be updated one-by-one, so that's not a workaround. I'm wondering if there's something along the lines of the progress spinner that actually blocks any updates/triggering until "released" so I can change many widgets while only updating the plot once?

Something along the lines of:

with pn.block_updates():
    slider1.value = val1
    slider2.value = val2
    slider3.value = val3
    slider4.value = val4

I also tried disabling the widgets up front (slider.disabled = True), but that only prevent the user from interacting with them.

I could make a fully working example with some toy data if the code above is unclear.
