Riiight. XIP_KERNEL is enabled, which means no alternatives are
permitted, but that R9A config option selects the Andes errata, which in
turn depends on alternatives.

I suppose we could do something like (untested):
diff --git a/drivers/soc/renesas/Kconfig b/drivers/soc/renesas/Kconfig
index 7b74de732718..6fe85255e2ce 100644
--- a/drivers/soc/renesas/Kconfig
+++ b/drivers/soc/renesas/Kconfig
@@ -343,7 +343,7 @@ config ARCH_R9A07G043
        select ARCH_RZG2L
        select AX45MP_L2_CACHE if RISCV_DMA_NONCOHERENT
        select DMA_GLOBAL_POOL
-       select ERRATA_ANDES if RISCV_SBI
+       select ERRATA_ANDES if (RISCV_SBI & RISCV_ALTERNATIVE)
        select ERRATA_ANDES_CMO if ERRATA_ANDES
        help
          This enables support for the Renesas RZ/Five SoC.
