Custom colorbar tick labels for bokeh

Is it possible to use custom labels

import xarray as xr
import hvplot.xarray
zz = xr.tutorial.open_dataset('air_temperature')
zz.hvplot('lon', 'lat').opts(colorbar_opts={'ticker': {273: 'freezing', 280: 'above'}})

Similar to:

import xarray as xr
import hvplot.xarray
hv.extension('matplotlib')
# zz = xr.tutorial.open_dataset('air_temperature').isel(time=0)
tst = zz.hvplot('lon', 'lat').opts('Image', cbar_ticks=[(273, 'freezing'),])
