Dnsmasq - Increase cache size

Hi all,
I gave up on AdGuard Home and switched back to a simple dnsmasq. I installed the AddOn and everything works as it should, the only thing that bothers me a bit is the cache size. The default value of 150 entries is simply not enough (looking at the dnsmasq logs you see all the different URLs/Domains called when your home network is idle; all those Apple, Google and Amazon devices “calling home”. Just those fill the cache. It would be good if all those addresses be cached as well as all the other stuff.

So here’s my question: is it possible to set the cache size to e.g. 500?

(I did try to do this in the AddOn Config by adding an entry:
cachesize: '500'
but that did not work.)

The default value of 150 was set back in the day when memory was expensive (150 entries = (max) 14,1KB; 500 entries = 47KB. On my 8GB PI4 there is plenty of space…)

Here’s the statup Log showing the actual cache size of 150:
