+# Configures kernel options to enable or disable eBPF and BTF debug information.
+#
+# This function adjusts kernel configuration settings based on the value of the global
+# variable KERNEL_BTF and the amount of available system memory. When KERNEL_BTF is set
+# to "no", the function disables all debug and BTF options (while leaving eBPF options unchanged).
+# Otherwise, it checks if the system has at least 6451 MiB of available RAM. If memory is
+# insufficient and KERNEL_BTF is not explicitly set to "yes", the function exits with an error.
+# When sufficient memory is available or KERNEL_BTF is forced to "yes", it enables eBPF and BTF
