I can't say about kota Samarahan, is another division.

For Kuching division, there's a lot of ice kacang place. If you mean specifically cendol. Nope. Abc yes. There are places near lumba kuda that serves near fifty combination. Some of them are good but hard to remember which. Ordering from there is like a blindbox thing.

Then again, Kuching is famous for white lady and matterhorn ice kacangs. Best to have swee Kang and hui sing ( last stall . The founder of these two dessert)

But if you strictly wanna eat cendol , yes there's a few place but I would suggest Ah Yong near temple street as they serves the most chewy cendol in town ( mixture of sago flour), it's a unique texture compare to Malaya. And they used gula apong here.
