How to invest in / buy government bonds?

They aren’t present in the list of approved securities for getting collateral margin. This likely would be the reason for that -

There’s an issue in allowing these bonds for pledging. The clearing corporation requires us to have 90% in liquid assets. This means that you’ll also need to have 90% in cash of the margin required for your positions when you use collateral margin received from pledging corporate bonds. In other cases, this ratio is 50-50 i.e., out of the margin required at least 50% has to come in cash and liquid assets, and the remaining 50% can come in the form of equity collateral.
