Thank you for posting in the Intel Communities. Since your question is related to the Intel® FPGA Acceleration Cards we are moving this topic to the Intel® High-Level Design community.
If you would like to use the BMC and update the board then it is recommended to install the accelleration stack. If you are only testing the OneAPI then you do not need to install it. You may refer to https://software.intel.com/content/www/us/en/develop/documentation/installation-guide-for-intel-oneapi-toolkits-linux/top/installation/set-up-a-system-for-fpga-with-the-intel-pac/install-intel-fpga-add-on-for-oneapi-base-toolkit-package.html for how to setup the FPGA for OneAPI.
