Band Pass filter to dataset with topographic masking

I want to use 20-100-day band-pass filter to the anomalous u850 data from MERRA Reanalysis.
But the region in high mountains (e.g. the Himalaya/ Tibetan plateau) is masked with missing values in the dataset.
So, the "band_pass_latlon_time" function is not allowing me to filtering the dataset.
What is the alternate way to use the filter?
With regards,
