Catalina: how can I download bootcamp support files after I have successfully installed bootcamp?

2 months ago I successfully set up bootcamp / WIN 10 on my MacBookPro 16".

Since I did erase the USB Drive with the bootcamp support files, I need to download them again.

However, if I start bootcamp utility it tells me that it will erase the Windows partition before I even get to the dialog allowing me to download the bootcamp support files.

Is it safe to proceed in bootcamp utility without losing my bootcamp partition?

Is there an alternative and safe way for downloading the bootcamp support files?

Thank you
