To update your version of Node using nvm, do the following:

nvm --version

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash
3. Once nvm is installed, check your current version of Node by running the following command: 
node -v
4. Then update your version of Node using the following command:   
nvm install node --reinstall-packages-from=node
5. And finally, verify that your update is complete by rechecking your Node version:   
node -v
