Terraform doesn't obey conditional git config for github ssh

[ghost]

This issue was opened from my professional account by mistake.
Please visit the clone: #31255

Cloning an enterprise github repo with ssh that is part of a conditional config ends with git@github.com: Permission denied (publickey).

##Git config - main

[includeIf "gitdir/i:C:/XXX/Repos/"]
    path = C:\\XXX\\.gitconfig

##Git config - C:\XXX\.gitconfig

[core]
sshCommand = "ssh -i c:\\\\XXX\\\\.ssh\\\\XXX.pkey"

Running git pull works correctly:

> git pull
Enter passphrase for key 'c:\XXX\pkey':xxxxxx
...pulling... 

Running terraform init:

Downloading git::ssh://git@github.com/XXXXXX?ref=v1.0.0 for tags...
╷

Additional Info

I ve tried the ssh config file and it works, but this way I have only one key for all github projects.
SSH config that worked:

Host github.com
   HostName github.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/id_rsa_hub
