How to connect to git lfs file on github?

thanks it helped if you want to change your whole model but still is not a great solution. 
It has to be LFS file by design it is higher than 100 mb and I am looking to get this file using power query and provided sha.

What about Custom Git Connector? 

I have one, maybe here i could post the statement like here

I have Github connector like here:

// GitHub Connector for Power BI (Standard GitHub OAuth)
[Version = "1.0.0"]
section GitHub;

client_id = "minenumber";
client_secret = "minenumber";

[DataSource.Kind="GitHub", Publish="GitHub.Publish"]
shared GitHub.Contents = (relativePath as text, optional folderPath as text, optional branchName as text) =>
    let
        baseUrl = "https://api.github.com/repos/Company/",
        refBranch = if branchName <> null then "?ref=" & branchName else "?ref=develop",
        url = relativePath & "/contents/" & folderPath & refBranch,

        source = Json.Document(Web.Contents(baseUrl, [
            RelativePath = url,
            Headers = [
                #"Authorization" = "Bearer " & Extension.CurrentCredential()[access_token],
                #"User-Agent" = "PowerQuery"
            ]
        ]))
    in
        source;

GitHub = [
    Authentication = [
        OAuth = [
            StartLogin = (resourceUrl, state, display) =>
                let
                    authorizeUrl = "https://github.com/login/oauth/authorize?" &
                        "client_id=" & client_id &

                        "&state=" & state
                in
                    [

                    access_token_response = Json.Document(Web.Contents("https://github.com/login/oauth/access_token", [

                        ]

                    access_token = access_token_response[access_token]

    ]
];

GitHub.Publish = [
    Beta = true,
    Category = "Other",
    ButtonText = { Extension.LoadString("ButtonTitle"), Extension.LoadString("ButtonHelp") },
    LearnMoreUrl = "https://powerbi.microsoft.com/",
    SourceImage = GitHub.Icons,
    SourceTypeImage = GitHub.Icons
];

GitHub.Icons = [
    Icon16 = { Extension.Contents("GitHub16.png"), Extension.Contents("GitHub20.png"), Extension.Contents("GitHub24.png"), Extension.Contents("GitHub32.png") },
    Icon32 = { Extension.Contents("GitHub32.png"), Extension.Contents("GitHub40.png"), Extension.Contents("GitHub48.png"), Extension.Contents("GitHub64.png") }
];

Still need help on this!
