Terminal entry command: xattr -d com.apple.quarantine file_path

I am afraid that if I enter this command into the my Terminal app, that my MacBook Pro (Big Sur circa 2014) will then be open to allowing malware onto my computer if by chance I click on something nefarious:

xattr -d com.apple.quarantine file_path

Am I correct in my concerns? Or, if the command is 'safe' to enter, can you tell what that command does for me?

I am asking this as the "xattr -d......" Terminal command was given to me by a very reputable vendor of ham-radio tools. I was told by them that it will then allow me do to download their tools to update their firmware on one of their handheld devices I recently purchased.

Here is a link to their download page if you wish to see it for yourself:

Thank you,
