Sorry I was thinking these thermostat bolt holes went through into the chamber below but of course they do not.
A small tungsten carbide bit will remove both the bolt and drill stem but go carefully as it will remove aluminium even quicker and may be kicked sideways by the hard drill stem. A small ball shaped tip may be your best option
The carbide bits are extremely hard and you can get them in many shapes for a dremel but they are expensive at about $30 each. Used on Aluminium they last forever on steel or cast iron their life is much shorter.
You can also get diamond tipped dremel drilling bits intended for drilling holes in glass and ceramics that may work also.
If you have oil leaks to fix then perhaps best to live with your temporary repair until you have time to pull the engine for the oil leaks and then you can tackle this repair at the same time.
