4. Open the downloaded json file with a notepad, modify the vminc details in "vmnicsToUplinks" section and save the file
5. On the VCF Installer UI select "DEPLOY USING JSON SPEC"
6. Click "CHOOSE FILE" and select the modified json file from Step # 4
7. Proceed with the next step to validate & deploy
