How to invest in Bharath Bond without slippage?

The bid ask spread is more than 1re, I am looking to purchase for more than 5L. Whats the best way to do it?

Bharat Bond ETF doesn’t have much volumes. So it’ll not be possible to execute this big order in one go. Of the 5 listed Bharat Bond ETF’s, EBBETF0431 had the most trading volume, around 9,000 quantity. Best to place limit order and wait for it to fill.
