use nf-core on an HPC with internet access

[Donbbit]

Description of the bug

Hello, I would like to ask if it's necessary to use nf-core on an HPC with internet access. After installing the software, I submitted a job using qsub, and I received the following error:

ERROR ~ Error executing process > 'NFCORE_ONCOANALYSER:WGTS:READ_ALIGNMENT_DNA:BWAMEM2_ALIGN (1)'

try to remove the defaults channel from the config, your admin might have blocked that

Should I remove the below in .nextflow/assets/nf-core/oncoanalyser/nextflow.config :
conda.channels = ['conda-forge', 'bioconda', 'defaults']
