Question Windows/Ubuntu Dual Install Issue with Intel RST

I have a laptop Acer Aspire A515-54G (128GB SSD & 1TB HDD) with windows 10 installed in the SSD. Recently, I needed to install Ubuntu in dual boot, so I shrinked the HDD since it had free space. But Ubuntu installation failed since Intel RST was enabled.

I google the issue and followed this article. Please have a look.

Following the article, I changed the storage device driver to Microsoft Storage Spaces Controller and then from the BIOS I changed the SATA settings to AHCI. All according the article.

Please help me out how can I fix this issue?
